PDF online reading task requirements:

1. Security: PDF text data cannot be set to Web Sharing (non-public path). Normal users can only browse and download, and authorized users can print and download.

2. Keyword highlighted display: Special Text in PDF can be highlighted.

Preliminary Experiment ideas:

1. normal HTTP path display is not allowed, that is, the display PDF cannot be read through the Adobe PDF plug-in IE, because the user can copy and save the PDF without security.

2.convert a PDF file to SwF online using ipv2swfe.exe in swftoolsto disclose SWF to users and control the security of SWF. Security: A. SWF files are randomly generated and deleted after use. B. The SwF in the cache is cleared when the client closes IE.

3. Keyword display: through FLEX statement programming, control the happy display of keywords in SWF.
