<p><P>PROBLEM TO BE SOLVED: To provide a method for encrypting and decrypting information security. <P>SOLUTION: Regarding a method for encrypting information security, cipher protection is performed upon a file in a prescribed operation process by security measures. Regarding a method for decrypting information security, a user authority is read to protect the encrypted file and if the encrypted file can be decrypted by the user authority, the encrypted file for which decrypting operation is completed, is further encrypted to protect the file. At the same time, decrypting and re-encrypting processes are prevented by a conceal mode from being displayed on a user operation screen, user operational inconvenience is reduced, and the encrypted process is effectively prevented from being destroyed by other person. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
