Electronic Data Interchange (EDI) - Security Issues

The paper checks and balances that exist within the clerical world are not possible with EDI. While rare, the possibility that data will be intercepted and stolen or altered in transit does exist. Messages also may be deliberately or mistakenly duplicated. This can result in overcharges, wasted resources, and damaged relations between trading partners. For these and other reasons, companies take measures to ensure accuracy and security, including security policies that limit the authority to engage in transactions to certain individuals; means of verifying that messages sent were received intact (electronic "seals"); the use of proper encryption methods; digital signatures or bio-metrics (the use of human attributes like fingerprints or voice) to verify the identity of senders and receivers; audits that verify the accuracy of electronic records; efforts to ensure that translation software has been written correctly and not altered; and so on.
