About |
In alliance with AppraisalWorld™ (www.appraisalworld.com), an online community for Valuation Professionals, Appraisal Matrix, LLC has created a method of securing the authenticity and integrity of appraisal reports, and the ability to verify that information has not been manipulated from the original file. The core technology is based on Data Matrix technology, which is widely used for authentication purposes. Appraisal Sentry is an online system, which uses a 2-D barcode and a strong 512-bit complete digest of the PDF appraisal report for protection. All of the data on the report will be protected on a server with the digest hash code, which uniquely identifies each file. It's the industry standard for comparing files. Bar coding technology appeared more than 30 years ago. Now linear bar codes can be found everywhere. However, conventional barcodes have some inherent limitations—most importantly the amount of data encoded. Two-dimensional (2-D) codes like Data Matrix overcome this key limitation by encoding information digitally. This high data capacity is ideal for document security and data encryption. Data Matrix codes can generally store up to 2335 alphanumeric
characters, text, numbers, bytes of data, digital signatures, and
photos. (2-D) codes are typically not replacing conventional barcodes
in their applications, but instead extend barcode applicability
to areas where they have not been applied in the past. U.S. Government Agencies, Which Have Adopted
