Method and device for privacy respecting data processing

A method of data processing, the method comprising the steps, in a device comprising a processor, of:

• obtaining encrypted data to process;
• obtaining privacy attributes associated with the encrypted data, the privacy attributes defining processing requirements a data processing task should respect to be allowed to process the encrypted data or to output a result of data processing of the encrypted data;
• obtaining a script and a signature for the script;
• verifying the signature;
• and
• if the signature is successfully verified:
• decrypting the encrypted data to obtain decrypted data;
• executing the script to process the decrypted data to obtain a result;
• and
• outputting the result;
• the method further comprising the step of comparing the privacy attributes and processing attributes of the script, the processing attributes defining processing requirements respected by the script to determine if the script respects the privacy attributes.
