The invention relates to a method for securely providing a personalized electronic identity on a terminal () which can be used by a user () for identification purposes when claiming an online service. In the method, an identification application is ran on a terminal (), which is assigned to a user (), in a system comprising data processing devices () and said terminal (), and additionally a personalization application and an identity provider application are ran. The method has the following steps in particular; transmitting a request to transmit an identity attribute assigned to the user () front the personalization application to the identity provider application; transmitting the identity attribute from the identity provider application to the personalization application after an agreement to transmit the identity attribute by means of the identity provider application is received from the user (); generating an asymmetric key pair with a public and a private key on the terminal () by means of the identification application; transmitting the public-key from tire identification application on the terminal () to the personalization application; and generating an electronic certificate for the public-key by means of tire personalization application and storing the electronic certificate in a data storage device in order to form a first public-key infrastructure of the personalization application, additionally having the steps of: generating a hash value for the identity attribute and recording the hash value onto the electronic certificate. The identity attribute is encoded and transmitted together with the electronic certificate from the personalization application to the identification application () on the terminal (), where both are stored in a local storage device of the terminal ().
