In a system for providing access control management to electronic data, techniques to secure the electronic data and keep the electronic data secured at all times are disclosed. According to one embodiment, a secured file or secured document includes two parts: an attachment, referred to as a header, and an encrypted document or data portion. The header includes security information that points to or includes the access rules and a file key. The access rules facilitate restrictive access to the secured document and essentially determine who/when/how/where the secured document can be accessed. The file key is used to encrypt/decrypt the encrypted data portion. Only those who have the proper access privileges are permitted to retrieve the file key to encrypt/decrypt the encrypted data portion.

Methods and systems for providing access control to secured data

To grant or deny access rights to a user attempting to access a protected system or secured electronic data, an access right evaluation process is carried out among all applicable policies including those embedded in the secured electronic data. In a preferred embodiment, the access right evaluation process is invoked only when a system being accessed is protected or a file being accessed is detected to be in a secured format. Further, the access right evaluation process is configured preferably to operate transparently to the user. The access right evaluation may be advantageously used in systems or applications in which devices, mediums or electronic data are secured and can be restrictively accessed by those who are authenticated and have proper access privilege.

Dynamic evaluation of access rights

Techniques for dynamically altering security criteria used in a file security system are disclosed. The security criteria pertains to keys (or ciphers) used by the file security system to encrypt electronic files to be secured or to decrypt electronic files already secured. The security criteria can, among other things, include keys that are required to gain access to electronic files. Here, the keys can be changed automatically as electronic files transition between different states of a process-driven security policy. The dynamic alteration of security criteria enhances the flexibility and robustness of the security system. In other words, access restrictions on electronic files can be dependent on the state of the process-driven security policy and enforced in conjunction with one or more cryptographic methods.

Method and system for securing digital assets using process-driven security policies

Techniques for providing pervasive security to digital assets are disclosed. According to one aspect of the techniques, a server is configured to provide access control (AC) management for a user (e.g., a single user, a group of users, software agents or devices) with a need to access secured data. Within the server module, various access rules for the secured data and/or access privileges for the user can be created, updated, and managed so that the user with the proper access privileges can access the secured documents if granted by the corresponding access rules in the secured data.

Methods and systems for providing access control to electronic data

An improved system and method for providing a security system with the capability to stage a modification to its operation is disclosed. Staging the modification before actually modifying normal operation of the security system allows the impact of the modification on the security system to be examined prior to deployment. If the staging of the modification to the security system is deemed successful, the modification can be fully deployed with reduced risk of unexpected security lapses or other detrimental consequences.

Security system with staging capabilities

Techniques for managing files in a designated location are disclosed. An example of the designated location is a folder, a directory, a repository, a device, or a storage place. A set of access rules is applied to a designated location such that all files in the designated location shall have substantially similar security. As a result, secured files can be easily created and managed with respect to the designated location and users with access privilege to the designated location can access most of the files, in not all, in the designated location.

A distributed intelligence network using time and frequency domain multiplexing. On power-up, each node determines its skew and requests downloading of program code and configuration data. A node claims timeslots by transmitting a packet into an apparently empty timeslot and verifying receipt of its own packet.
