Method and apparatus for applying digital signatures to translated content

A system for applying digital signatures to translated content, comprising:

• a presentation device;
• a first user interface presented on the presentation device;
• and
• at least one processor operates to:
• create the first user interface in a first language as part of an application and digitally signing the first user interface to create a user interface signature;
• enable the entering of data into the first user interface and digitally signing the data by a first user to create a data signature;
• translate the first user interface to a second user interface in at least a second language and digitally signing the second user interface to create a translated user interface signature;
• present the data to at least a second user using the application;
• and
• verify the digital signatures, wherein a verification of the digital signatures verifies the data signature, the user interface signature, and the translated user interface signature, wherein the steps of digitally signing the data and independently verifying the signatures provides non-repudiation of both the data entered by the first user and the first user interface translated to the second language;
• verify the data signature by:
• retrieving and re-digesting the data entered into the first user interface into a new digest, wherein the re-digested data includes a source user interface digest, and
• comparing the new digest with a stored data digest;
• and
• verify the user interface signature by:
• retrieving and re-digesting the first user interface to create a copy of the source user interface digest, and
• comparing the copy of the source user interface digest with a stored source user interface digest.

A computer program embodied in a non-transitory computer storage medium and when operated in a data processing machine for applying digital signatures to translated content, comprising instructions which when executed by the data processing machine that cause the data processing machine to:

• create a first user interface in a first language as part of an application and digitally signing the first user interface to create a user interface signature;
• enable the entering of data into the first user interface and digitally signing the data by a first user to create a data signature;
• translate the first user interface to a second user interface in at least a second language and digitally signing the second user interface to create a translated user interface signature;
• present the data to at least a second user using the application;
• and
• verify the digital signatures, wherein a verification of the digital signatures verifies a data signature, a user interface signature, and a translated user interface signature, wherein the steps of digitally signing the data and independently verifying the signatures provides non-repudiation of both the data entered by the first user and the first user interface translated to the second language;
• verify the data signature by:
• retrieving and re-digesting the data entered into the first user interface into a new digest, wherein the re-digested data includes a source user interface digest, and
• comparing the new digest with a stored data digest;
• and
• verify the user interface signature by:
• retrieving and re-digesting the first user interface to create a copy of the source user interface digest, and
• comparing the copy of the source user interface digest with a stored source user interface digest.
