Method and Apparatus for access secured electronic data are disclosed. According to one aspect, an off-line access mechanism in a client machine is activated to facilitate those users on the go to access secured electronic data. When a user decides to be away from a network premises or on a business trip, an off-line access request may be generated by the off-line access mechanism and forwarded to a server. In response, the server may grant the off-line access request to the user as well as the client machine from which the user will access the secured electronic data off-line. Depending on implementation, the AC may provide amended or tentative access rules, access privileges or user keys that will automatically expire when a predetermined time ends or become invalid the next time the client machine is connected to the server.

Method and apparatus for accessing secured electronic data off-line

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

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.

Managing secured files in designated locations

Techniques for securing electronic data and keeping the electronic data secured at all times are disclosed. According to one embodiment, a client module in a client machine is configured to provide access control to secured documents that may be located in a local store, another computer machine or somewhere over a data network. The client module includes a document-securing module configured to operate in a path through which a document being accessed is caused to pass so that the document can be examined or detected for the security nature. If the document is secured, the document-securing module obtains a user or group key to decrypt security information in the secured document for access rules therein. If a user accessing the document is determined to have the access privilege to the secured document, a file key is retrieved from the security information and a cipher module is activated to decrypt the encrypted data portion with the file key. Likewise, if a document is to be secured, the cipher module encrypts clear data from the document to create the encrypted data portion. The document-securing module integrates proper or desired security information with the encrypted data portion to produce the secured document.
