Businesses and individuals involved in commercial transactions or messaging activities need to have confidence in, and be trusting of, any communication that is sent in relation to that activity. This helps to ensure that documents sent electronically have not been altered in any way, that the sender can be easily recognised, and that the document has the necessary security.Trust is the basis of business and commercial activity, and can be enhanced by the use of electronic signatures and trust services. Generally, electronic signatures and trust services can prove the origin of the communication or document, show whether a message has been altered and ensure messages remain confidential.More and more businesses and individuals are using, or are seeking to use, electronic signatures and trust services and, with an increasing number of Government services available digitally, there will be continued growth in this market for some time to come.
