Description

System and method for certifying volunteer activities}

The present invention relates to a service authentication system and a service authentication method using the same.

Volunteering refers to acting at one's will for the benefit of society or the public. Volunteers are activities that have many positive elements for both the volunteer and the recipient. Volunteers can also receive mental rewards such as rewards and experiences through volunteering activities, and thereby enrich their quality of life. In addition, if there is a shortage of hands to perform the necessary work, the side receiving the service can be provided with free or very low cost manpower in short or long term.

However, the management of volunteerism has become an important issue as the school recognizes the number of volunteers as a result of volunteering, and the company recognizes new employees as volunteering as a social experience or experience.

In consideration of this, the conventional service example “Patent Service Relaying and Management Method and System” of Patent No. 10-0445532 connects volunteer activities between volunteer applicants and volunteers based on shareholder and day of week rather than date values. It provides relaying and management methods and systems for relaying and managing the status of volunteering in real time, and provides input ease to selectively enter various types of volunteering dates for volunteering. And, it has the advantage of being able to improve the efficiency of computerized management on the date of volunteering.

However, the prior art has a problem in that management for cases in which a real volunteer and a person who wants to receive service certification are different from each other is insufficient. In other words, if the person himself or herself has not performed the service and wants to be certified that he or she has performed the service performed by another person, there is a problem that it is difficult to recognize and sanction it at the demanding place for certifying the service. In addition, there is a problem in that when attempting to be certified that the service has been performed, personal information for identifying the volunteer is likely to be leaked to others, including the place where the service activity is demanded.
