Figure 11: Activation of a CodeMeterAct license by telephone With “activation by telephone”, an installation identification number (hash) is created for the existing license information file on the user’s PC and consists of the Host-ID and the product serial number. The end-user informs the developer’s help line of both this installation identification number and the product serial number over the telephone. When using the CodeMeter License Central (see chapter 8.2 CodeMeter License Central – The Core) the developer calculates the activation code, recites it to the user, who then types it into the application activation window. The license is then activated. If a developer wants to implement the automatic activation or activation by telephone he is provided with API functions to integrate activation into his software and into his design. For the automatically protected application (see 7.1 AxProtector) you will find an implementation example in the error message dll. Developers are also able to automate the “activation by telephone”. Here, a voice-controlled computer or a web page is used instead of a person. In this case, the end-user types in the installation identification, and receives the result by telephone or display. When using activation by telephone you have two basic options for coding the installation identification and the activation code: Alphanumeric mode: use of 40 alpha-numeric characters (0 .. 9, A..Z), length: 40 characters Numeric mode: use of 10 numbers (0..9), length: 60 characters Using an API function you are able to switch between the two options. The numeric code option requires a greater length but has the advantage that the installation code is easy to enter with telephone keys when a voice-controlled computer is linked. The numeric telephone transfer of the activation code is also easy because internationally 10 numbers are easier to spell than alphanumeric characters. 23 | 44
