Abstract
Techniques for ensuring the security of forms data are disclosed. The layout for a particular form is signed separately from the data used to fill out the form using encryption techniques. The signed data is related to the signed layout in a way which permits the layout to be changed without requiring the data to be changed while still guaranteeing that a changed layout does not change the original meaning of the signed data.
