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.
