FIELD: physics, computer engineering.

SUBSTANCE: invention relates to computer engineering. A data cache management device comprises one or more processors and memory which stores executable instructions which, upon execution by a processor, enable to: obtain permission-accessible data from a data server, wherein the permission-accessible data have associated data permissions which define one or more permissions needed by a requesting user to access the permission-accessible data; store the permission-accessible data and a cache signature corresponding to the permission-accessible data; receive and hash a first data request from a first user to obtain a cache signature; retrieve user permissions corresponding to the first user and comparison thereof with data permissions to determine that user permissions corresponding to the first user intersect with data permissions; after which a subset of permission-accessible data, which corresponds to said intersection, is determined; and send said subset of permission-accessible data in response to the first data request for the permission-accessible data.

EFFECT: providing faster access and delivery of data.
