A computer network-based messaging system controls the content of messages sent by users. A database includes permitted words and replacement text elements corresponding to at least one permitted word. A message filter receives an entered word or phrase input by a user on a messaging device as part of a message. The message filter replaces the entered word in the message with a corresponding replacement text element stored in the database. A message sending part transmits the message including the replacement text element over a data network for viewing by other users only if every entered word in the message is included in the database. The message sending part transmits the message even though one or words contained in the replacement text element are not permitted words in the database. The system may allow deletion of a replacement text element from a message only in its entirety.

Disclosed are a method, system, program and data structure for implementing a records retention policy by storing selected files for designated lengths of time and then deleting them only when that time has passed. Embodiments of the invention perform this function in an efficient database-free manner. Embodiments of the invention can perform this function by utilizing existing storage directory tree functionality provided by any computer operating system organized under a retention directory coupled with a mechanism for preventing unauthorized deletions of files designated for retention. Expiration of retained files may be managed through directory structure using directory names corresponding to expiration dates determined from identified retention periods for retained files. Files may be further protected from erasure by a kernel mode process which prevents erasure of any files contained in the retention directory.

The invention relates to a data backup system based on fingerprints, belonging to the technical field of computer storage backup, which aims at reducing management, storage and network overhead of data backup and improving backup performance. The invention comprises a backup server, a backup agent, a storage server and a Web server which complete data backup and recovery through mutual network communication.

Even when setting a complicated spam judging condition, it is possible to reliably determine a necessary electronic mail in reality (i.e a mail that is not a spam mail), without deleting a necessary electronic mail or the like. Based on the assumption that an electronic mail from a mail address to which transmission was performed in the past has a high possibility of not being a spam mail, a transmission destination mail address of an electronic mail transmitted to outside the organization is recorded as a permitted mail address (Step 506-Step 510), and when a transmission source address of an electronic mail destined to inside the organization matches a mail address registered in a permitted mail address database (Step 511: Yes), processing is performed to unconditionally receive this electronic mail (Step 504).

A single atomic instruction is used to change up to four disjoint areas in memory concurrently in an extended compare and swap operation, replacing traditional locks for serialization and providing recovery for all queue manipulations. Use count-based responsibility passing is employed so that any number of tasks can read the various message queue chains, concurrent with queue updates being made. A summary queue update sequence number is maintained to provide concurrent chain update detection, so that any number of tasks can add elements to the end, or remove elements from the middle (i.e. any where in the chain) concurrently. Concurrent footprinting is used with chain manipulation, so that all (or none) of the chaining indicators and a footprint are set with a single, non-interruptible instruction, making it possible for recovery to always take the correct action. One such use of concurrent footprinting is the concurrent footprinting of use count changes, while another is the transfer of ownership of message queue control blocks. In a preferred embodiment on an IBM S/390 platform, the Perform Locked Operation (PLO) instruction is used to perform the extended compare and swap operations.
