ABSTRACT:
The present invention leverages selections of data locations and comparative analysis of data values stored in these locations to provide a secure means of maintaining data integrity with minimal computational burdens. This provides, in one instance of the present invention, a tamper-resistant process to ensure that software application usage data is protected from malicious attacks. By storing and recalling data in an untraceable fashion, the present invention substantially increases the effort required to spoof the stored data. Additionally, comparative analysis is utilized with the randomized approach to facilitate in maintaining consistency of the stored data both in retrieval of information and when storing new data values. This allows checking of the data prior to overwriting sensitive data, thwarting malicious attacks that spoof new data as a means to alter the stored data.
