With AssinadorBR, any document that can be opened by cell phone (eg a PDF document) can be signed with the application. To do so, the user must create his account at AssinadorBR, which performs security checks, entering certain personal information, and registering his mobile device. With the creation of the account, a document received by any means of communication by the user (email, WhatsApp, Telegram, etc.) can be opened in the SubscriberBR application to be signed. The signature is authenticated cryptographically, guaranteeing the security of the information. Also, the signature and the hash of the signed document are registered in blockchain, making both inviolable.
In addition to the mobile part, there is a web layer of the application, which acts in the management of subscription requests, making, therefore, a control of who can or cannot sign electronic documents.
