Data security in a cloud computing environment

One or more tangible non-transitory device-readable media with device-executable instructions that, when executed by a cloud computing system, direct the cloud computing system to perform steps comprising:

• monitoring events at a node in the cloud computing system;
• on detection of an event of a specified type, interrupting a message associated with the event;
• selecting a security template from a set of security templates based on data in the message and at least one parameter associated with the message, the at least one parameter being one of:
• a User ID, a Session ID, a Server Location, a channel type, a Device ID a Transaction Type, or a time, the security template including a location of at least one data element within the data in the message and an obfuscation method to be applied to the at least one data element;
• applying the obfuscation method to the at least one data element within the data in the message according to the selected security template to create modified data;
• inserting the modified data into the interrupted message in place of the data in the message;
• and
• releasing the message.

A cloud computer system comprising:

• a processor;
• and
• a memory arranged to store computer executable instructions which when executed cause the processor to:
• monitor events at a node in the cloud computer system to detect events of a specified type;
• interrupt a message associated with a detected event of a specified type;
• select a security template from a set of security templates based on data in the message and at least one parameter associated with the message, the at least one parameter being one of:
• a User ID, a Session ID, a Server Location, a channel type, a Device ID, a Transaction Type, or a time, the security template including a location of at least one data element within the data in the message and an obfuscation method to be applied to the at least one data element;
• apply the obfuscation method to the at least one data element within the data in the message according to the selected security template to create modified data;
• insert the modified data into the interrupted message in place of the data in the message;
• and
• release the message.
