In 64 bit computers the drivers used have to be digitally signed. Digital signature is a special security mark on a driver or a document that preserves the authenticity of the document. A digital signature indicates the company which has published the driver so that you can verify whether any content has been altered by any unauthorized mean. Many drivers are modified after release which can also be determined by digital signature.
