Transferable Records
The legal validity of Electronic Transferable Records (e.g. legally validating the use of electronic records for negotiable instruments, warehouse receipts, etc) was explicitly established in UETA and ESIGN but significant business, legal and technology uncertainty remains about more specific practices and rules needed to support stable use and reliance at wide-scale.

Digital Signatures, Contracts and Records

Building Blocks of Legal Identity and Enforceable Signatures

- Report: In the 1990’s, the ABA Digital Signature Guidelines provided a conceptual framework for legally understanding and working with cryptographically based digital signatures. This document provides an excellent overview of how hash digests and public-private key cryptography can be used to legally execute a digital signature, though some of the more speculative content about a possible role of “trusted third party” new models of business to provide “certification authority” functions did not pan out.
