METHODS AND SYSTEMS FOR PROVIDING ACCESS CONTROL TO SECURED DATA

摘要

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.

1. A storage device, comprising:
a memory storing a secured file; and a processor configured to execute modules comprising: a verification module configured to send a file access request to an access control management module and receive a response to the file access request from the access control management module, the file access request being based on a request to access the secured file; and a document securing module configured to decrypt the secured file when the response indicates that the access control management module grants access to the secured file, wherein the access grant to the secured file is based on permissions for a user associated with the request to access the secured file, wherein the processor is further configured to provide the decrypted file in response to the file access request.
