Access-controlled encrypted recording method for site, interaction and process monitoring

Abstract

A high level of security for access to recorded information is provided by a method which includes provisioning of a trusted/protected communication linkage such as a tamper-resistant or tamper evident enclosure, a physical close coupling between information source and encryption processor and/or obfuscated code or end-to-end network encryption and encryption, possibly symmetrical, of the information to be recorded by a preferably random session key or segment key. The session key or segment key may then be encrypted, preferably asymmetrically, by a secure key which may be shared or access thereto shared in accordance with any desired security policy. Use of a public key or public key/private key infrastructure also provides for authentication of the recorded information.
