1. What is a digital ID?
Digital ID-s are the electronic equivalents to peoples' identity cards. You can present the Digital ID electronically to prove your identity or your right to access information or services online.
Digital ID-s, also known as digital certificates, bind an identity to a pair of cryptographic keys. This pair (the private and public key) can be used to sign and encrypt digital information. A Digital ID makes it possible to verify someone's claim that they have the right to use a given key. Used in conjunction with encryption, Digital ID-s provide a more complete security solution, assuring the identity of all parties involved in an electronic transaction. A Digital ID is issued by a Certification Authority (CA) and signed with the CA's private key.
A Digital ID typically contains the:
- Owner's public key
- Owner's name
- Expiration date of the public key
- Name of the issuer (the CA that issued the Digital ID)
- Serial number of the Digital ID
- Digital signature of the issuer
Digital ID-s ensure the authenticity of the author of the electronic document.
The authenticity of the paper document is defined by the signature, moreover, the signature itself can be authorized using a stamp or even by a notary. When it comes to the electronic documents, they are signed using a digital signature, which not only defines the author, but is strictly linked to the contents of this document. Any changes applied to the document without author's consent can be easily detected. Signing a document, verifying its authenticity, decrypting or encrypting can be easily done using modern cryptographic methods based on the pair of cryptographic keys.
2. What is a mobile ID?
Mobile ID or Mobile Identity is a development of the traditional online authentication and digital signing; the SIM card of one’s mobile phone works as an identity tool.
Mobile Identity enables legally binding authentication and transaction signing for online banking, payment confirmation, corporate services, and consuming online content. The user’s certificates are maintained on the telecom operator’s SIM card and in order to use them, the user has to enter a personal, secret PIN code. When using Mobile Identity, no separate card reader is needed, as the phone itself already performs both functions.
In contrast to other approaches, the mobile phone in conjunction with a mobile signature-enabled SIM card offers the same security and superior ease of use than for example Smart cards in existing Digital identity management systems. Smart card-based digital identities can only be used in conjunction with a card reader and a PC.
3. What is a Cloud / Saas Service?
Software as a service (SaaS) is a software delivery model in which software and associated data are centrally hosted on the cloud by independent software vendors (ISVs) or application service providers (ASPs).
It is sometimes referred to as "service(s) as a software substitute" (SaaSS) or "on-demand software".
SaaS is typically accessed by users using a thin client via a web browser. SaaS has become a common delivery model for many business applications, including office & messaging software, DBMS software, management software, CAD software, Development software, gamification, virtualization,accounting, collaboration, customer relationship management (CRM), management information systems (MIS), enterprise resource planning (ERP), invoicing, human resource management (HRM), content management (CM) and service desk management.
One of the biggest selling points for SaaS is the potential to reduce IT support costs by outsourcing hardware and software maintenance and support to the SaaS provider.
