20120137130System and Method for Providing Multi-Location Access Management to Secured Items - A system and method for providing access management to secured items through use of a plurality of server machines associated with different locations are disclosed. According to one embodiment, a local server can be dynamically reconfigured depending on a user's current location. Upon detecting that a user has moved to a new location, the local server for the new location can be reconfigured to add support for the user, while simultaneously, the local server for the previous location is reconfigured to remove support for the user. As a result, security is enhanced while the access management can be efficiently carried out to ensure that only one access from the user is permitted at any time across an entire organization, regardless of how many locations the organization has or what access privileges the user may be granted.05-31-2012
20110307937SECURITY SYSTEM FOR GENERATING KEYS FROM ACCESS RULES IN A DECENTRALIZED MANNER AND METHODS THEREFOR - Improved system and approaches for decentralized key generation are disclosed. The keys that can be generated include both public keys and private keys. The public keys are arbitrary strings that embed or encode access restrictions. The access restrictions are used to enforce access control policies. The public keys are used to encrypt some or all portions of files. The private keys can be generated to decrypt the portions of the files that have been encrypted with the public keys. By generating keys in a decentralized manner, not only are key distribution burdens substantially eliminated but also off-line access to encrypted files is facilitated.12-15-2011
20110296199METHOD AND SYSTEM FOR PROTECTING ELECTRONIC DATA IN ENTERPRISE ENVIRONMENT - Even with proper access privilege, when a secured file is classified, at least security clearance (e.g. a clearance key) is needed to ensure those who have the right security clearance can ultimately access the contents in the classified secured file. According to one embodiment, referred to as a two-Opronged access scheme, a security clearance key is generated and assigned in accordance with a user's security access level. A security clearance key may range from most classified to non-classified. Depending on implementation, a security clearance key with a security level may be so configured that the key can be used to access secured files classified at or lower than the security level or multiple auxiliary keys are provided when a corresponding security clearance key is being requested. The auxiliary keys are those keys generated to facilitate access to secured files classified respectively less than the corresponding security or confidentiality level.12-01-2011
20110258438System and Method for Providing Different Levels of Key Security for Controlling Access to Secured Items - With files secured by encryption techniques, keys are often required to gain access to the secured files. Techniques for providing and using multiple levels of keystores for securing the keys are disclosed. The keystores store keys that are needed by users in order to access secured files. The different levels of keystores offer compromises between security and flexibility/ease of use.10-20-2011
20100205446MULTI-LEVEL FILE DIGESTS - 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.08-12-2010
20100199088Method and System For Securing Digital Assets Using Process-Driven Security Policies - 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.08-05-2010
20090254972Method and System for Implementing Changes to Security Policies in a Distributed Security System - Improved approaches for effectuating changes to security policies in a distributed security system are disclosed. The changes to security policies are distributed to those users (e.g., user and/or computers) in the security system that are affected. The distribution of such changes to security policies can be deferred for those affected users that are not activated (e.g., logged-in or on-line) with the security system.10-08-2009
20090150546Protecting Encrypted Files Transmitted over a Network - An improved system and approaches for protecting secured files when being used by an application (e.g., network browser) that potentially transmits the files over a network to unknown external locations are disclosed. According to one aspect, access to secured files is restricted so that unsecured versions of the secured files are not able to be transmitted over a network (e.g., the Internet) to unauthorized destinations. In one embodiment, processes operating on a computer system are monitored to determine destination locations, if any, of said processes, and then using such destination locations to determine whether to permit the processes to open files in a secure or unsecured manner.06-11-2009
20090100268METHODS AND SYSTEMS FOR PROVIDING ACCESS CONTROL TO SECURED DATA - 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.04-16-2009
