Embodiment Construction

[0038] figure 1 A communication system 1 is shown in which a plurality of requesters can access data stored in a data store, such as a database. Within the communication system, data is stored within the access system 10 and access to the data is controlled through the access system.

[0039] Access system 10 includes a plurality of nodes or elements 12 , 14 , 16 , 18 and 20 . These include data sources 12 that receive or generate data to be stored and subsequently accessed. The data source 12 is connected to a first database 14 . The key generator 16 is connected to the first database 14 and is additionally connected to the second database 18 . The access controller 20 is connected to the first database 14 and the second database 18 .

[0040] The key generator 16 is connected via a first network 22 to a plurality of requestors 24A, 24B and 24C. Access controller 20 is also connected to requestors 24A, 24B and 24C via second network 26 , for example.

Abstract

Methods, systems, devices, and computer programs for enabling access to data by a requester. Generate multiple collections of data. The one-way function is then used to generate a plurality of keys each associated with a respective one of the plurality of sets. The information associated with the data within the specified set is used as input to the one-way function when generating the key for the set. Assign keys to requestors. The requester can then use the received key to generate a data access request. Upon receipt of the key, access to the data can be achieved. The requestor may then generate authentication data from information associated with at least a portion of the received data and authenticate the received data by comparing the authentication data with data derived from the received key.

Description

technical field [0001] The present invention relates to devices, systems and methods for enabling access to data, and in particular, to enabling multiple requesters to access data. Background technique [0002] In many communication systems, it is desirable to control access to data. In particular, it is desirable to have a system in which different requestors are allowed to access certain data portions within a given data block while preventing access to other data portions. Also, it is desirable to allow different parties to access the same data portion of the data without, for example, having both parties access all the same data portion; ie, allowing overlapping access by parties, but not necessarily consistent access. [0003] One example of providing such a system is described in US 2005 / 0180573. In this example, the data block is divided into multiple parts. Each portion of the data is then encrypted using a different portion-specific key. The requesting party is ...
