幾乎所有能夠在 Windows 環(huán)境下打開(kāi)的數(shù)據(jù)文件,包括私有軟件,可以被 CrypKey DLM 保護(hù),包含:
- 音頻和視頻(例如.au、avi、.fla、.mpg、.mp3、.wav、.wma 和 .wmv)
- 動(dòng)畫(huà)(例如.swf)
- 文檔(例如.doc、.pdf、.ppt、.pub 和.xls)
- 幫助(例如.hlp)
- 圖像和圖表(例如.bmp、.eps、.gif、.jpg、.tif,)
- 網(wǎng)頁(yè)(例如.htm、.html)
CrypKey DLM 工作方式是保護(hù)和綁定文件到計(jì)算機(jī)或 CrypKey USBKey,因而阻止了非法復(fù)制??梢栽谌魏蜗薅〞r(shí)間,例如60分鐘、60天或60次使用,訪問(wèn)文件。CrypKey DLM 也提供許多可選安全控制權(quán)限可以附加到文件上,例如:
- 打?。ɡ鐝牟荒艽蛴∑聊坏娇梢酝暾蛴。?/li>
- 保存至……(例如從不能在任何機(jī)器上保存到可以完整保存)
- 修改(例如從不允許文件修改到允許大量修改)
- 發(fā)布(例如從不能發(fā)布任何文件到完整發(fā)布)
- 網(wǎng)絡(luò)發(fā)布(例如從特定服務(wù)器到任何服務(wù)器)
- 查看時(shí)間(例如查看時(shí)間從30分鐘到365天)
- 打開(kāi)(例如從只能打開(kāi)一次到不限次數(shù))
- 電腦訪問(wèn)(例如從特定電腦訪問(wèn)到任何電腦)
附加到文件的安全控制權(quán)限一直在文件上存在,無(wú)論誰(shuí)嘗試訪問(wèn)該數(shù)據(jù)。CrypKey DLM 保護(hù)的文件可以綁定到一個(gè) CrypKey USBKey,這樣受保護(hù)的文件就被限制在一個(gè)的用戶范圍內(nèi)。
CrypKey DLM 可以保護(hù)存儲(chǔ)在幾乎所有地方的數(shù)據(jù)文件,包括:
- 附加到電子郵件的,甚至在該郵件發(fā)送之后的數(shù)據(jù)
- 存儲(chǔ)在可移動(dòng)數(shù)字媒體設(shè)備(例如 USB 存儲(chǔ)器、CD 和 DVD)的數(shù)據(jù)
- 在 FTP 站點(diǎn)發(fā)布的數(shù)據(jù)
- 存儲(chǔ)在桌面或網(wǎng)絡(luò);文件保護(hù)可以被設(shè)置為即使系統(tǒng)管理員也不能查看機(jī)密或商業(yè)秘密文件。

Virtually any data file that can be opened in a Windows environment, including proprietary software, can be protected by CrypKey DLM, including:
- audio and video (e.g., .au, .avi, .fla, .mpg, .mp3, .wav, .wma, and .wmv)
- animation (e.g., .swf)
- documents (e.g., .doc, .pdf, .ppt, .pub, and .xls)
- help (e.g., .hlp)
- images and illustrations (e.g., .bmp, .eps, .gif, .jpg, .tif,)
- Internet pages (e.g., .htm, .html)
CrypKey DLM works by protecting and binding files to a specified computer or CrypKey USBKey, thereby thwarting illegal copying. Authorized access can be issued for any restricted time period time that you specify, such as 60 minutes, 60 days, or 60 uses. CrypKey DLM also offers several optional security control rights that you can assign to your file, such as:
- print (i.e., no print screen ability to full-printing privileges)
- save to . . . (i.e., save file on no machines to full save features)
- change (i.e., no allowed file changes to permitting many changes)
- distribution (i.e., no file distribution to full distribution)
- network distribution (i.e., specified server versus any server)
- viewing time (i.e., file viewing allowed from 30 minutes to 365 days)
- open (open file one time to an unlimited number of times)
- computer access (open file on a specified computer to any computer)
The security control rights assigned to the file always stay with the file, regardless of who attempts to access the data. CrypKey DLM-protected files can be bound to a CrypKey USBKey, where the protected data is limited to a specified number of uses.
CrypKey DLM protects data files that are stored almost anywhere, including:
- attached to an , even after the is sent
- stored on a portable digital media device (e.g., USB drive, CD, and DVD)
- posted on an FTP site
