About the client Signum Technologies is a secure and reliable e-signature service system for businesses and individuals. The company was founded by a professional group of specialists who are passionate about innovation. Signum’s mission is to help people and businesses reap the benefits of digital transaction management. Business challenge The task of our team was to create technology for signing and approving all types of documents online, including bank forms, tax documents, insurance paperwork, invoices, contracts, proposals, leases, and other housing and rental agreements. This e-signature service has to comply with security standards and combines best practices in reliability and authentication Result Our team developed an unique product that makes electronic signing easy without compromising on data security. We have implemented verification algorithms based on face recognition that obtains clients photos, analyzes, and records his unique biometric parameter. Our face identification system is able to determine whether a face is “alive”, so photo can’t be used to excess to the records. With Signum you will be able to perform multi-signing process of various types of documents, invite other users to Signum, send reminders to other signers and check signing status. We implemented multifactorial identification by using face and voice. We also implemented a security system based on BlockChain for Smart Contracts. Its main advantage is that document (contract) is validating by the Ethereum system during the signing. It is distributed among several hundred and even thousands of computers around the world. Data stored on the BlockChain is generally considered incorruptible.
