Problems solved by technology

Unfortunately, digital information can be easily deleted, altered and/or manipulated.
The industry has been addressing these deficiencies by several means, including the use of WORMs (Write Once Read Many) devices, the use of digital signatures, redundant off-site storage managed by different people, etc., but all of them have aspects to demand a more efficient solution: WORMs are slower than any other storage device and one risk is that a drive can be replaced by another one tampered; digital signatures have a high computational cost that makes impossible to use standalone in systems with significant transaction volume and do not prevent the change of order; and duplicating the storage systems and administration have cost issues and difficult the further audit process.
The state of the art is based today in the use of digital signatures (Public Key Infrastructure based) accompanied by an accurate date and time stamp to provide authenticity

Embodiment Construction

[0030]The present invention proposes to generate fine granular integrity to huge volumes of data in real time, involving the following steps:[0031]a) receiving the data. An API (Application Programming Interface) (600, 505) is provided to enable the communication with the different data sources;[0032]b) processing the data applying cryptographic routines (510, 610) to generate one or more immutable digital chains that contain at least the original data related integrity information including timestamps; and[0033]c) communicating said digital chain(s) to the appropriate receiver (620), that could be the same as the sender of data (312), a different one (311), a storage media (320), etc.

[0034]The system described herein is preferably implemented as a software program, platform independent Java implementation, running in standard hardware. However, the system may be implemented in various embodiments using other well known implementations, such as, for example, Microsoft's .net technol...

Abstract

A method and system to generate fine granular integrity to huge volumes of data in real time at a very low computational cost. The invention proposes a scalable system that can receive different digital data from multiple sources and generates integrity streams associated to the original data. This invention provides full guarantees for data integrity; the order of data logged cannot be altered and content cannot be modified added or deleted without detection.

Description

FIELD OF THE INVENTION[0001]The present invention relates to digital data integrity and more particularly to a technique to detect malicious tampering at a very fine granular level without the performance constraints of purely using digital signatures.BACKGROUND OF THE INVENTION[0002]Today, almost all critical business records are generated, managed and stored electronically, creating efficiencies and cost-savings for businesses. Unfortunately, digital information can be easily deleted, altered and / or manipulated. For businesses, the burden of proof is on the company to ensure and attest to the accuracy and credibility of their electronic business records. This ability to prove the integrity of critical business records becomes especially important in litigation where executives are often called upon to support their claims of ownership of any discoverable records, as well as verify their history of creation and use.[0003]It is important to remark the difference between involuntary ...
