Can DRM be better?

hello,
I have read many forums on DRM for pdf version of books. However, the comments on DRM, were 99% unhappy ones'
So i just want to ask Adobe technical employees, if it is possible to modify the PDF to be created or already created using Adobe tools to do the following,
- Restrict copying content, editing content (though highlighting is possible), printing
- Restrict emaling (Avoiding attachments), uploading (i know these 2 would be not possible, but still placing a thought)
- Allowing the PDF to be copied only once after downloading it (keeping in mind, multiple devices available to read & users might like to read the book at multiple places
- Also while copying, it must not be considered as a copy when placed on pen drives, CDs etc, but only when placed on PC, cell phones ipad etc. Also if the pdf is opened from external digital media, then considered it as a copy & no more copies can be created. (This can be done by setting an internal counter on file created)
By usng this process, DRM can be protected not upto 100%, but for sure upto some good extent, i think. If you guys want to discuss on it more, please do let me know.
Thanks

Adobe LiveCycle DRM can prevent content being extracted or edited.
While it's possible to assign a license to a DRM-protected file that allocates it to a particular device, there is no legal way to stop someone transferring a file, either by disc copying or email. The only method that can do that is to secretly install 'rootkit' software behind the operating system to restrict low-level access to discs. That was once tried by a music publisher to stop people ripping CDs, they ended up in court and were taken to the cleaners. Never going to happen again.

  • Can DRM manage the hierarchies of non-Oracle products

    Hi,
    1. Can DRM manage the hierarchies of non-Oracle products. (For example, does it have an ability to interface with and manage the internal hierarchies of Guidewire( A claims system))?
    2. does DRM interact with ODI to achieve that type of integration.
    Appreciate your response..

    DRM is an independent or stand alone application. Even other applications like IBM cognos and SAP apps also uses DRM as their master data management tool.

    Can DRM support multiple currency ?

    Hi,
    DRM is a master data management tool - so if you have a currency dimension, then yes it would be easy to manage multiple currencies.

  • Can Labview be better than vendor software for Zymark robot operation?

    I am trying to decide on alternate software to for programing Zymark Zymate and Benchmate systems. Thank you.

    Of course my first reaction is, "Of course you should use LabVIEW." But I may be a bit biased in that direction. It's a question that's really up for debate.
    Since LabVIEW is nothing more than a programming language, it can be both better and worse than the vendor software. It really depends on how you code the application.
    I know nothing about either of the systems you mention, but from the other response, it seems they just rely on serial commands to operate. LabVIEW is very good at serial communication. However, if the vendor software does everything you need, then you probably wouldn't gain much from writing your own version in LabVIEW, or any other language for that matter.
    However, if the vendor software is lacking some features you want or nee
    d to use, or maybe you just don't like the user interface, then it would be worth a shot at making your own. What language you use should really depend on which one you are most comfortable with. If you've been coding in some flavor of C for years, then you may some problems throwing something together quickly in LabVIEW to do what you want. On the other hand, if you're new to programming, then LabVIEW would be a good choice. It's very easy to learn the basics and have something running quickly, but there's more than enough depth to the environment to make a very powerful program.

  • How can i take Better pictures from my Sony Cybershot DSC-HX9V like DSLR?Kindly Best Settings...

    How can i take Better pictures from my Sony Cybershot DSC-HX9V like DSLR?Kindly Best Settings...

    Taking better pictures on an HX9v isn't something you can just 'do'. It takes learning and creativity.
    Understanding how the camera works, and having a good imagination to use it.
    Look at phone cameras for example, amazing photos.
    If you're talking about image quality, that is, less noise, crisp sharp photos, etc, compact cameras in general just won't match the DSLR.
    If you're talking about photos that look stunning, again, learn how to use the camera, and be imaginative (creative)
    I have a couple of articles to understand the basics to a camera (I really need to find the time to add more) on my website:
    http://d3studio.com.au/
    One thing I'm definitely lacking on there is composition, and that's something you can learn on YouTube - compositions in a photo is very important when you're first starting out.
    Put your 9v onto M (manual) mode, and try out the different things - learn how the camera works, think about what you want to shoot, and then do it.
    Good luck.

    If it's slow on startup it would be extensions loading or LaunchDaemons starting up. 
    You should have a look in:
    /Library/LaunchDaemons
    /Library/Extensions
    You can count out anything in your home folder and it shouldn't put anything in /System as that's reserved for Apple. 

  • ¿Can be a better resolution in the external display?

    I recently buy a new LCD ViewSonic 22" full HD (its declared to support 1920X1080) and Im very happy with my acquisition. Now I can work in a large screen with Page and Final Cut Pro but still I feel it can be a better resolution in the bigger display the same as in the little 13" in my MBP 7.1 Indeed the display resolution it's 1080p in the LCD and 1280X800 in the little screen. I would like to ask if I did the right settings and if not what can I do? If it is possible of course.
    Thanks in advance
    Josef Carel

    No worries man .. your concern is known as pixel width or pixels per square inch..
    you do the maths by multiplying horizontal inches with vertical inches of your display
    that's your display area in square inches ..
    and then you multiply 1920 x 1080 ..
    that's your total number of pixels
    when you divide the area to the number of pixels you get pixels per inc
    and the higher the value the smaller each individual pixel therefore harder for your eye to spot them resulting in smoother display ..
    That's why I've advised you the 22 inch display in the first place and I'm sure now you appreciate the advice more

  • Can I get better time resolution than 1ms in labview?

    Hello,
    I am trying to generate an external waveform which requires timing to be in the microsecond range, I was trying to use the wait function to define the timing dt but found that I could not get below 1 ms. I tried to specify timing in the microsecod range by overloading the wait function with a float (0.200) to represent 200 us but found behavior to be erratic. Again, I am trying to create a waveform for extenal hardware which does not support buffering and requires software to drive.
    Thanks!
    Joel Abdullah

    "I am trying to create a waveform for extenal hardware which does not support buffering and requires software to drive."
    Sorry but that simply can not be done in a Windows environment due to the limitaions of the OS (1KHz was "way-fast" when WIndows replaced DOS).
    It can be done in a Real-Time OS like Pharlap for example.
    Attempts to deterministically perform any operation at a rate faster than 1KHz in a non-deterministic OS can be best described as an "exercise in futility."
    Trying to help,
    Ben
    Note to Waldermar:
    Timed loops can perform rather well at 1KHz or even better if you have a hardware clock available.

  • Can DRM ebooks be read on a Sony E2 ereader

    On successfully downloading a DRM ebook onto our PC, it can be loaded onto the Sony E2 E-Reader, but cannot be opened. Adobe DRM is authorized.

    I have four examples. I rechecked them all. They are all listed in my Purchases under the Books category on the iTunes Store.
    They are all unprotected (listed as "Purchased Book"). I was able to open them all in Adobe Digital Editions, and could read them. They are:
    (1) Third class in Indian Railways - Gandhi (a Project Gutenburg book)
    (2) iOS Human Interface Guidelines - Apple
    (3) IPAD User Guide for iOS 4.3 - Apple
    (4) Office 2010: The Missing Manual - sold by O'Reilly which doesn't apply DRM to their books. This is the only one I paid $ for.
    I would probably have more from the iBookstore but I usually get my O'Reilly books direct from the publisher (also without DRM).

  • RSSI... can i get better than -80 dBm ???

    i would like to know if i should be able to get better than RSSI = -80 dBm (signal strength)... i have four bars (usb ec168 modem) whenever verizon is running at it's best here in northeast oklahoma... a former alltel region... my understanding is that RSSI = -80 dBm is the level that is described as "good enough for Rev A / evdo"...
    in my research of this subject googling all over... i find that some people will get RSSI in the 70s and 60s... lower being better / stronger signal... can someone tell me why i cannot get these kinds of levels since i often have four bars showing 90-100% ???
    when my RSSI drops to less than -80 dBm... higher values such as -85, etc... this is when my evdo drops to 1xrtt and even DO...
    appreciate any enlightenment on this subject... thx!
    *obviously, verizon (if you are listening...), since i am paying for 3g broadband... i would like to have 3g broadband, rather than the 1xrtt and DO that happens so very often, evenings, during the week!

    Understood.  Actually, if you mean the towers are neither VZ or Alltel because the carrier name is not listed, it won't be.  Your service may not be from a tower per se either.  If there are antennas in the area, that may be where your signal is from.
    The towers are listed by the owner and the carriers  lease space on them along with the antennas.  The sure way to tell is to use your cell phone if you have a VZ phone and do a field test with it since you have a desktop and cannot move it about.  The closer you get to the "site" of your signal source, the stronger your signal.  evdoforums.com can assist with a list of codes for each brand of cell or smartphone to help you determine this.  I also have this if you may need.
    Actually, -80dbm is not a bad signal and from my experience, a small percentage get better than that.  The best possible is -50.
    I wonder why this is even an issue since you have not reported any problem with speeds, connection or any problems that may be associated with the signal strength.  If there truly are only 3 towers and no antennas in your area then the reason is more than likely due to congestion.
    I have also discovered that the signals, connections, etc. are all improving and doing an update for your PRL if that is possible through your software may just be the fix.
    However, if you are insistant on spending money on antennas and/or amps, etc. when the signa isn't anywhere near abnormal, that is your choice.  Keep this in mind if you do, you may not have a gain in more than 10 dbm if you have any at all.
    So have a great day and good luck.

  • How can I get better picture quality?

    it seems like the picture quality could be better.

    Why would expect the picture quality to be better?  The camera on iPad was designed with one thing in mind - Facetime.  The rear camera is 1.3 Megapixel.  The front camera is .7 megapixel.  Neither are even close to an inexpensive point and shoot camera and not even the same camera as is supplied with iPhone 4.  Sorry you're disappointed, but it's not camera quality.  Now, that said, in bright light, the rear facing camera can take an acceptable picture.  In lower light, it will be grainy as the specs would suggest. 

  • How can I get better reception?

    I live on a farm on the edge of the Hampton Roads VA area (Norfolk, Newport News, Virginia Beach).  Customer service tells me I'm about 3 miles from the nearest cell tower.  The MiFi reception seems to work well enough, but since I work remotely half the time, I run out of GB's even though I'm on the largest plan right before the end of each billing month.  To avoid the outrageous over charges, I switch to using the hotspot function on my Droid for the last few days of each billing month. 
    The signal for that device is lousy and have a difficult time even staying connected.  Had to restart the hotspot 5 times to complete the registration here and write this post.
    I don't have access to DSL or any cable services (if I did, I'd drop my Verizon Wireless non-voice services completely).
    Does anyone know of or can suggest any way to boost signal for better service?  I have called customer service numerous times and they don't seem to either know or want to help. 

    Hello.  I have two suggestions that might help your situation.
    Assuming you work indoors and that it degrading your signal, you could get a "booster" (no, not those cheesy stick-on things from TV).  I live in a "black hole" for cell reception and purchased a Wi-Ex Zboost signal amplifier.  There are different models and also other companies that make them.  Basicall it's an amplifier.  You put a foot-long tube on your roof (or probably in your case, you would need a directional antenna) and run coax into the area where your home office is.    Here is a link that should help.   http://www.wi-ex.com/solutions.aspx  You can get add-on antennas so you don't necessarily have to get the professional model.
    The other suggestion, since you indicated a willingness to change providers, is to go with a satellite system.  Probably the most expensive system, but just another suggestion.
    Good luck.  Hope that helps.

  • X-Fi Xtreme, WinXp SP3, chronic volume fading, can't use beta dri

    Hello,
    Per the new beta driver that's being reviewed in another thread, the into says "This download is a?beta driver providing Microsoft? Windows Vista? and?Windows?XP support for Creative Sound Blaster? X-Fi? series of audio devices..."
    Except for the X-Fi Xtreme, that is. Way down at the bottom of the intro there is this note:? "Do not install this driver for Sound Blaster X-Fi Xtreme Audio."
    Well, that's my card. I'm running XP SP3 after successfully downgrading two PCs from Vista Ultimate. The sound on the other PC is OK with an Audigy2, but this machine has the X-Fi Xtreme and it's experiencing all sorts of weird symptoms.
    I uninstalled everything, including the card, and reinstalled it with the latest driver on the support page, XFXA_PCDRV_LB__04_0079.exe. This had no effect on the problems.
    In any surround sound mode: when the card first starts playing back any audio source - stream, DVD, audio file - the volume for all frequencies except bass quickly fades. Within seconds only bass remains and continues playing until I get sick of hearing it and turning the source off.
    If I set the mode to quadrophonic, or any other setting except surround, the fading does not occur;? but then the volume of all frequencies goes up and down with a period of 3 or 4 seconds.
    Per what I said above, I can't use the beta driver so I'm currently working with the one that came with XFXA_PCDRV_LB__04_0079.exe?
    Does anyone have any ideas about what I can do to fix this problem?
    Thanks for your time,
    Big Al Mintaka?

    UPDATE 08/2009:? Today I used Creative's auto-update program install the latest driver v.4.80 for my X-Fi Xtreme. ? It didn't do anything to fix the fade problem I first reported back in 09/2008.
    So I looked around the forum and found Daniel's latest support pack SB P7X Series Support Pack .6 (05/4/2009). I tried that, but still no change, the fade problem persists in all surround modes. In all other modes, the audio still starts oscillating up and down after 2-3 sec.
    Right. Many thanks to Daniel for all the hard work you've done trying to support Creative's products. NO thanks to Creative.
    So I'm going to trash the X-Fi. I know this next question is considered lame in a product's forum, but given my experiences with Creative I don't see how it could hurt: can anyone recommend a good **non-Creative** audio card for a 5. system? Here are the particulars:
    PC: Dell Dimension 8300 3.2GHz .0GB RAM
    OS: Windows XP SP3
    Video: ATI Radeon 9800 XT 256K
    Audio: Creative X-Fi Xtreme/NFG
    350GB Maxor Internal HD (2)
    Speakers: Logitech Z-5500 THX-cert. 505-watt 5. digital surround system with digital equalization
    Thanks to all for your time,
