A method, program and system are provided for securing electronic transactions. A payment card processor server computer receives a payment authorization request message, the payment authorization request message being generated in response to an electronic payment transaction request made by a user, wherein the payment authorization request message includes first encrypted payment account information for a first payment device. The payment card processor server computer receives a first hardware device ID associated with a first hardware device that generated the payment authorization request message, wherein the first hardware device is associated with a user payment account for the user. The server computer determines that the first encrypted payment account information from the received payment authorization request message matches the first hardware device ID, and the purchase request is completed.

Securing online transactions via hardware identification

Techniques for parallel data collection and recovery for a failing virtual processing system are disclosed. According to aspects of the present disclosure, an example method includes: detecting that the virtual processing system experiences an irreparable error; saving, by each of a plurality of processors of the physical processing system, a corresponding context and data stored in an allocated portion of a memory of the physical processing system to a data store; selecting one of the plurality of processors as a recovery processor; initializing, by the recovery processor, a pre-determined reserved portion of the memory; initiating, by the recovery processor, a new instance of the virtual processing system on the reserved portion of the memory while each remaining processor of the plurality of processors continues the saving; and dynamically adding each remaining processor of the plurality of processors to the new instance of the virtual processing system.
