Electronic Time Stamping

Hongkong Post is partnering with The Chinese University of Hong Kong on providing e-timestamping service for the Internet and e-commerce community. Electronic Time-Stamping (e-TS) is a secure online notary mechanism, which certifies that a set of data has existed and has not been altered since a specific point in time. It serves as a trusted third party witnessing the existence and particulars of electronic data.

Regardless of the format and the content, any electronic data can be timestamped. e-TS can be applied to online business transactions, e-mails, secure messaging, intellectual property protection and other time-sensitive services.

A FREE trial to create your own timestamping is available online now. You can visit in Hongkong Post website or click to have a free trial and get more details.

    Starting from April 2004, Hongkong Post's new root certificate ("Hongkong Post Root CA 1") was admitted to the Microsoft Root Certificate Program, in addition to the old root certificate ("Hongkong Post Root CA") which had already been admitted in July 2003. The program aims at protecting Microsoft customers from security issues related to the use of public key infrastructure (PKI) certificates. This means that Internet Explorer and Outlook Express users of Windows XP and Windows 2003 will now trust certificates issued by Hongkong Post under the two root certificates.

    Users on platforms before Windows XP can also pick up and install the two Hongkong Post root certificates to their operating systems when they perform the Windows Update at URL, Please note that Root Certificate Update is not a critical update and users need to explicitly click-open the optional Windows 98/ME/NT/2000 Update list to include the Root Certificate Update.

    The admission of Hongkong Post to the Microsoft Root Certificate Program is a solid proof of the trustworthiness of the Hongkong Post CA System and e-Cert.
