Mission Critical recommend E-Lock ProSigner from Frontier Technologies.

E-Lock ProSigner enables organisations, their customers and partners to sign and approve documents electronically and securely, through the application of PKI based Digital signatures. E-Lock ProSigner efficiently manages all your signing needs through automated features and wizards.  It integrates with your Microsoft applications for complete ease of use.

Digital signatures provide an electronic means to sign documents and web content, however the real significance lies in how these signatures are used within business processes. E-Lock ProSigner is the only product, which adds value to digital       signatures by providing features consistent with the business need of an organisation.

Business Need E-Lock ProSigner is an    off-the-shelf product, which immediately integrates within your existing workflow. It takes into consideration all aspects of corporate approval systems and efficiently manages all these.

 Approval Management Today's on-line business approval processes involve more than just digital signatures to documents. In approval systems, it is essential that documents created or authored need pass through pre-defined hierarchy for approval of contents. E-Lock ProSigner allows the     application of policies to such documents, which enforce that the document be      digitally signed only in the hierarchical    sequence specified by an organisation. This ensures that authorised personnel sign,  depending on levels of authority or as per pre-determined business procedure.

Restricted Access to high value documents  For confidentiality, access to contents of high-value business documents such as financial reports or Non Disclosure Agreements need to be restricted to   authorised personnel only. With E-Lock ProSigner documents can be encrypted for specified people, allowing only these people to view the contents.

Multiple Signatures Many business documents especially business contracts need to be signed by more than one party. To make it legally viable, all parties need to sign the exact contents of the document. With E-Lock ProSigner, multiple people can sign and approve the same document. An audit trial is also maintained which helps track approvals to the document. This audit trail creates accountability for each person in the signing process and serves as powerful non-repudiation tool. All signatures on the document can be independently verified. Any change to the content of the document will invalidate the previous signature.

 Like the signature you use on written documents today, digital signatures are now being used to identify authors/co-signers of e-mail or electronic data. Digital signatures are created and verified using Digital Certificates.

The potential of business opportunities and enhanced customer convenience services offered by the Internet is phenomenal.

From home banking to network shopping and online information subscription services, security remains a growing concern. Governing access control through the use of a simple password is no longer thought to be adequate.

- Controlling access through the use of a known quantity, the password, in addition to a possessed entity, the digital certificate, is much more secure.

- More and more companies doing business on the Internet are awakening to this reality and requiring the use of digital certificates by their customers.

However, it's not just online consumers that will need digital certificates, businesses operating electronic commerce servers on the Internet will need digital certificates as well. Here, because of the identity verification performed by the Certification Authority before issuance, the presence of a digital certificate will attest to the integrity of the business, thus providing online consumers with assurance that they are dealing with a legitimate business.

A Digital Signature is created using a Digital Certificate. How do Digital Certificates work? A Digital Certificate binds a public key to an individual or organisation. The binding of a public key to an individual or organisation is certified by a trusted source (usually a Certification Authority or CA). Digital Certificates are based on Public Key Cryptography, a scheme that uses public and private key pairs. The private key is known only by the owner and is used to create a digital signature. This key must be kept private at all times by the user. The public key is widely known and is used to verify the digital signature. Indeed, when you verify a digital signature, you want to know the identity of the person who has signed the message. A public and private key pair has no inherent association with any identity, it is simply a pair of numbers. This association is achieved in a Digital Certificate that binds the public key to an identity. A Digital Certificate makes it possible to verify someone's claim that they have the right to use a given key, helping to prevent people from using phoney keys to impersonate other users. Used in conjunction with encryption, Digital Certificates provide a more complete security solution, assuring the identity of all parties involved in a transaction.
