A medical image management system including an image archive server for storing image datasets received from a plurality of image acquisition computers and a plurality of display stations for displaying requested image datasets retrieved from the image archive server is provided with an authentication and security system which includes an authentication server for maintaining and storing hashes and timestamps, and for providing hash, timestamp pairs in encrypted form in response to requests from display stations. The image acquisition computers are configured for computing hashes and providing them and image dataset identifiers to the authentication server, receiving timestamps from the authentication server which are then inserted in the image datasets, and storing the image datasets in the image archive server. The display stations are configured for retrieving image dataset, computing hashes from retrieved image datasets, requesting and decrypting hash/timestamp pairs received from the authentication server, and comparing the hashes, and optionally the timestamps, obtained from the authentication server with those computed or extracted from the image datasets received from the image archive server.

To enable localising of the garbage collection procedure, reference stacks are provided for each thread stack frame such as to identify, preferably via a per-thread reference table, data objects referenced from only a single frame, which objects are deleted on conclusion of that frame.
