摘要：The development of webbased technology has been utilized by services that provide electronic certificates for their users. Along with the increasing number of users, the creation of electronic certificates in image or document format causes an increase in storage media on the server. This research uses an application program interface technology (API) on HTML5 Canvas with a 2D graphic rendering method. The data on the ecertificate is arranged with layers of image or text objects that have size, color, and coordinate properties. The results of implementing electronic certificates with HTML5 Canvas show that the use of storage media on the server is up to 90% more efficient. And the electronic certificate display is responsive on all devices as it scales with browsers. That way, web services for electronic certificates can be more economical, secure, and dynamic.
