====== ADUCID standard operations ======


The fundamental element of ADUCID®’s activity is an **operation**. 

  * The target application requests AIM to perform an operation, AIM along with PEIG® then perform the operation and make the result available to the application. 
  * The application can then use the result of the operation (e.g. use a positive authentication result to grant access to information to a specific user in the scope of that user’s assigned rights, or use a negative result to deny access). 
  * Standard applications only use the "open" operation, which performs user authentication. 
  * Applications that manage identities (Identity Management) use other operations that support the execution of the entire lifecycle of the identity and other activities. 

For illustration, a list of supported operations of ADUCID® is provided with a brief description of each operation:

|Item Initialization of an identity |II |Identity Initialization |"init" |PEIG® and AIM together form a new unique electronic identity. |
|Use of an identity |IU |Identity Use |"open" |PEIG® and AIM together validate the eID and provide a link to user information (authentication). |
|Change in an identity |IC |Identity Change |"change" |PEIG® and AIM together change the existing internal values of the identity while preserving the entire context of personification (including all associated personal data). |
|Termination of an identity |IE |Identity End |"delete" |PEIG® and AIM together invalidate the electronic identity and prevent anyone from performing any operation using this identity. |
|Reparative change of an identity |RC |Reparative Identity Change |"rechange" |Change of an identity performed if the validity of previous identity has expired. |
|Reparative initialization |RI |Reparative Identity Init |"reinit" |Identical with II, performed if corresponding identity exists on PEIG® (this operation’s purpose is to restore AIM). |
|Extended Use |XUSE |  |  |Advanced operation to create replicas, display dialogs and work with personal factor. |
