Abstract: In one aspect, a method and apparatus is provided for reducing ink consumption when printing electronic documents. An electronic document is processed to identify different elements of the document, such as images, text blocks, and advertisements. Once the element identification is complete, a score is assigned to each one of the elements. The scores are then compared against a threshold T and only elements whose scores exceed the threshold T are printed. By filtering out some of the elements of the electronic document, the method and apparatus conserves ink and other printer consumables.

Abstract: Multi-level file digests for electronic files are disclosed. A top level digest represents a single digest for the associated electronic file. Lower level digests represent digests for portions of the associated electronic file. The top level digest is derived from the lower level digests. The top level digest is useful for facilitating rapid comparison to determine whether electronic files are the same. In one embodiment, electronic files are encrypted with a block encryption scheme, and digests are efficiently calculated and stored on a block-by-block basis. Advantageously, when modifications to an encrypted electronic file occurs, only those modified blocks need to be processed to undergo decryption and re-encryption to determine the appropriate digest.

Abstract: An improved system and approaches for protecting passwords are disclosed. A file security system for an organization operates to protect the files of the organization and thus prevents or limits users from accessing some or all of the files (e.g., documents) associated with the organization. According to one aspect, a password entered by a user is used, provided it is authenticated, to obtain a respective authentication string (a relatively longer string of numbers or characters). The retrieved authentication string is then used to enable the user to enter the file security system and/or to access secured files therein. According to another aspect, user passwords are not stored in the file security system to avoid security breaches due to unauthorized capture of user passwords.

Abstract: Techniques for utilizing security criteria to implement document retention for electronic documents are disclosed. The security criteria can also limit when, how and where access to the electronic documents is permitted. The security criteria can pertain to keys (or ciphers) used to secure (e.g., encrypt) electronic files (namely, electronic documents), or to unsecure (e.g., decrypt) electronic files already secured. At least a portion of the security criteria can be used to implement document retention, namely, a document retention policy. After a secured electronic document has been retained for the duration of the document retention policy, the associated security criteria becomes no longer available, thus preventing subsequent access to the secured electronic document. In other words, access restrictions on electronic documents can be used to prevent access to electronic documents which are no longer to be retained.

Abstract: Improved approaches for providing notifications in a distributed file security system are disclosed. The file security system includes a file security server that manages file security for a plurality of clients. When security criteria (e.g., security policies or rules) change at the file security system, typically the clients need to be notified so that they operate in accordance with the correct security criteria. The security criteria impacts whether a particular client (or its user) are able to access certain files being protected by the file security system. A client can be notified in different ways depending on network characteristics. In one embodiment, an appropriate way to perform notifications between the file security server and clients can be automatically determined, thus advantageously minimizing user impact and allowing the system to transparently adapt to different networks.
