Conclusion

As signature policies emerge as important elements in certain transactions, they are likely to receive yet further attention where formalism in a transaction becomes critical. Signature policies are necessary elements that add to the safety of the transaction by identifying the conditions of usage and the terms of authorization of electronic signatures within and beyond the exchange of signed transaction data. Formally written signature policies can become invaluable for automated processes, such as those conducted by using open electronic commerce formats, e.g., XML, open EDI, etc. Signature policies add value to electronic signatures by providing information on the context of validation and verification of an electronic signature, as well as other constraints of their application. Signature policies can also enhance some management conditions in an open transaction environment by allowing more information to flow from the signatory to the receiver and ultimately add to the transparency of a transaction.

Due to the limited understanding of signature policies, there is a certain ambiguity surrounding their content and application. Although the usage of signature policies is likely to remain confined within large organizations where the need for backtracking authorization is more evident, signature policies can contribute to the integration of electronic signatures in existing applications and services, and enhance trust in transactions.
