  • Encryption and decryption system and method with content analysis provision
    Patent number: 6393568
    Abstract: A computer based encryption and decryption system and method provides content analysis through a content inspection mechanism, such as detection of a computer virus using a virus detection algorithm based on determining whether digital input information is encrypted. The content inspection mechanism analyzes decrypted content for such things as virus patterns, keywords, unknown program format, or any other content based criteria. The system generates a decryption request to decrypt encrypted digital input information prior to applying content analysis, such as virus detection.
