Abstract:
A method and system for generating trusted security labels in electronic documents is disclosed. The method comprises determining parts of the document to be cryptographically bound to the security label and hashing them; hashing the security label; specifying any necessary policies as signable signature properties; and digitally signing the collection of these items. The resulting security label is trusted, because it is digitally signed and its digital signature also covers the parts of the document to be protected, thus allowing any tampering of the security label or the covered parts of the document to be detectable. A corresponding system for generating trusted security labels is also provided.

Abstract:
The present invention relates to a multilayer transparent conducting electrode, comprising a substrate layer (1), an adhesion layer (2), a percolating network of metal nanofilaments (3) and an electrical homogenization layer (4), the said electrical homogenization layer (4) comprising: an elastomer having a glass transition temperature Tg of less than 20° C. and/or a thermoplastic polymer having a glass transition temperature Tg of less than 20° C. and/or a polymer, an optionally substituted polythiophene conducting polymer, and nanometric conducting or semiconducting fillers.
Abstract:
A method of metadata management is provided. Metadata associated with information objects is important in the management and classification of electronic information referred to as information objects. A metadata schema structure definition is defined enabling a metadata schema to be applied to the information objects to ensure consistent creation and management of hierarchical metadata across and organization and interoperability between different metadata schemas.
