CeDiploma FAQs

The CeDiploma is optional for graduating students. All CMU graduates are still issued a free paper diploma. However, the CeDiploma is a great option for students to have an official, secure, electronic version of their CMU diploma. It is completely portable and can be shared with employers, family, friends and on social media sites such as LinkedIn. 
You can obtain your CeDiploma through SIO, which has a direct link to CeCredential Trust, a third-party vendor of the university.
Currently, the CeDiploma is only available for CMU spring 2016 graduates and future graduates.
Yes, you can download a digitally signed copy of your CeDiploma. You can then email it to anyone you desire, and it will retain the Adobe Digital Signature and CeDiD for validation purposes.
For security, the CeDiploma is strictly intended for electronic portability, and therefore cannot be printed.

There are two ways to validate your electronic diploma. (This also is noted on the second page of the CeDiploma.)

  1. Validate through the CMU validation website or by clicking the link on the second page of the CeDiploma and typing the necessary information where indicated.
  2. If you are using Adobe Reader or Acrobat 9.0 or higher, you will be able to view the Digital Signature, which is shown at the top of the PDF, and is part of the overall security of the document. If the Digital Signature shows a Blue Ribbon, it means that the document has not been tampered with; any other symbol signifies the document cannot be trusted. 

Note: Other PDF/digital readers and some mobile devices may not be able to show the Digital Signature / Blue Ribbon.

CeCredential Trust is the branded name of the digital signature that Carnegie Mellon's vendor uses to digitally sign the CeDiploma.
This issue is due to the version of your operating system on your tablet, or the PDF viewer that the browser is using to open the CeDiploma. In the case of the iPhone/iPad, updating to the most recent iOS operating system usually solves the problem.
