AI Technical Summary

Problems solved by technology

In such a case, the user will not be able to access secure resources on the mobile client because there will be no connection to the LDAP server
In the case of a business environment, this can lead to severe loss of productivity

Embodiment Construction

[0011] The present invention will now be described with reference to the accompanying drawings. should understand figure 1 It is provided merely as an illustration of one implementation and is not intended to imply any limitation as to the environments in which different embodiments may be implemented. Many modifications can be made to the environments shown.

[0012] figure 1 A distributed data processing system, generally designated 100, is shown in accordance with one embodiment of the present invention. System 100 includes server computer 104, server computer 106, and memory 122 (which contains ACL table 124). A plurality of client computers 118 and 120 are coupled to servers 104 and 106 via a network 102 (eg, the Internet). Network 102 represents a global collection of networks and gateways that communicate with each other using the Transmission Control Protocol / Internet Protocol suite. At the heart of the Internet is a backbone of high-speed data communication lines...

Abstract

In a method for controlling access to an encrypted document, a computer receives a request to access the encrypted document, the access request comprising a user ID and a user password. The computer performs a one-way hash function on the user password to generate a hash value. The computer searches an access control table for the hash value which indicates an authorization for the user to access the encrypted document and corresponds to a document password encrypted with the user password. The computer decrypts the document password using the user password. The computer decrypts the encrypted document using the decrypted document password.

Description

technical field [0001] The present invention relates generally to document access control, and more particularly to access control to documents available from a network. Background technique [0002] Electronic documents may contain sensitive information to which access should be restricted. It is well known to encrypt sensitive electronic documents to prevent unauthorized access. In addition to encryption, access to restricted information is often controlled through the use of access control lists (ACLs). Typically, an ACL specifies which users can access protected data and the level of user access to protected data. The list may include an entry for each user with access rights. The ACL can be kept as a table on the local system or it can be kept in the cloud. [0003] "Cloud computing" is well known today and refers to accessing computing resources and data via a network infrastructure, such as the Internet. Computing resources and data storage can be provided by lin...
