The invention discloses a data validation, mirroring and error / erasure correction method for the dispersal and protection of one and two-dimensional data at the micro level for computer, communication and storage systems. Each of 256 possible 8-bit data bytes are mirrored with a unique 8-bit ECC byte. The ECC enables 8-bit burst and 4-bit random error detection plus 2-bit random error correction for each encoded data byte. With the data byte and ECC byte configured into a 4 bit×4 bit codeword array and dispersed in either row, column or both dimensions the method can perform dual 4-bit row and column erasure recovery. It is shown that for each codeword there are 12 possible combinations of row and column elements called couplets capable of mirroring the data byte. These byte level micro-mirrors outperform conventional mirroring in that each byte and its ECC mirror can self-detect and self-correct random errors and can recover all dual erasure combinations over four elements. Encoding at the byte quanta level maximizes application flexibility. Also disclosed are fast encode, decode and reconstruction methods via boolean logic, processor instructions and software table look-up with the intent to run at line and application speeds. The new error control method can augment ARQ algorithms and bring resiliency to system fabrics including routers and links previously limited to the recovery of transient errors. Image storage and storage over arrays of static devices can benefit from the two-dimensional capabilities. Applications with critical data integrity requirements can utilize the method for end-to-end protection and validation. An extra ECC byte per codeword extends both the resiliency and dimensionality.

A system, method, and computer program to reduce incorrectly declined transactions and improve risk calculation accuracy by reducing error probability during fraud detection. The tool first receives at least one data element as well as transaction account data and / or financial transaction instrument data. Then a customer is determined from a first record associated with the transaction account data and / or financial transaction instrument data. A record search is performed to identify at least one additional record associated with the customer. Finally, the data element is compared to the information contained in the additional record to create a comparison result that verifies a customer address. The comparison result may be used as an input to transaction risk calculations. The comparison result may also be provided to a merchant system and / or merchant for use in a decision-making process, for example, to verify customer identity.

A risk system that performs a risk assessment of a financial transaction to obtain a risk score. Based on the risk score, the risk system may request additional transaction information from a customer and / or a merchant. The request is based at least in part on financial transactions that are of moderate risk to thereby provide a non-cash payment acceptance service with more information to further evaluate the financial transaction risks. Thus, moderately risky financial transactions, that are likely to benefit the non-cash payment acceptance service and the merchant that subscribes to the non-cash payment acceptance service, are authorized for increased profitability and customer satisfaction. Furthermore, the risk system may approve or authorize financial transactions that generally fail standard risk assessments that use a cut-off risk score to divide the financial transactions into either approved or declined groups. As a result, the risk system is capable of re-evaluating some of the moderate risk cases for the purpose of securing beneficial financial transactions.

Verification means in the proof data verification device verify the signature, and if the verification is successful, the execution of program is allowed.

A forms engine allows data sharing between customizable on-line forms, such as college admissions applications. Before applying, an applicant opens an account with a third party application servicer. After the applicant completes an application for one institution, the data is saved in a data base and automatically populates fields in subsequent application forms. The form for each institution is created from a form description file. Each form is branded for its institution and forms for different institutions differ in appearance and content so that the presence of the third party servicer is transparent to the applicant.The system is extensible without programming, allowing new applicant attributes to be readily incorporated into the system and allowing the content and appearance of the application to be readily changed by changing the description file. The use of aliases for applicant attributes permits data to be readily shared between forms even though labeled and arranged differently on different forms. Information stored about each attribute allows the specification of data validation rules and data sharing and grouping rules, as well as dependency rules that permit application page content to depend on applicant's responses on a previous page.
