Storage module for storing a data file and providing its hash

A computer implemented method for storing a data file on a storage module of a computing device, comprising:

• loading, by the storage module, a data file from a data source into the storage module;
• computing, by the storage module, a hash value of the data file loaded into the storage module;
• making, by the storage module, said hash value available to a hash value consumer;
• establishing, by the storage module, a server-client dependency relationship with one or more data consumer(s), the storage module being a server and the one or more data consumer(s) being client(s) dependent on the server;
• granting, by the storage module, read-only access to the data consumer(s) for accessing said data file loaded into the storage module;
• and
• terminating the server upon detecting, by the storage module, any change and/or attempted change of the data file, propagating termination to each of its dependent clients, terminating all data consumers which have been granted access to the data file.

A computer program product comprising computer-executable instructions which, when executed by one or more processors of a computing device causes the computing device to perform a method comprising:

• loading, by a storage module of the computing device, a data file from a data source into the storage module;
• computing, by the storage module, a hash value of the data file loaded into the storage module;
• making, by the storage module, said hash value available to a hash value consumer;
• establishing, by the storage module, a server-client dependency relationship with one or more data consumer(s), the storage module being a server and the one or more data consumer(s) being client(s) dependent on the server;
• granting, by the storage module, read-only access to data consumer(s) for accessing said data file loaded into the storage module;
• detecting, by the storage module, any change and/or attempted change of the data file;
• and
• terminating the server upon detecting, by the storage module, any change and/or attempted change of the data file, propagating termination to each of its dependent clients, terminating all data consumers which have been granted access to the data file.
