There is provided an anonymous service method of providing local linkability. The anonymous service method providing local linkability according to exemplary embodiments of the invention, an anonymous authentication operation based on a short group signature is performed, for which the concept of a local linkability is introduced to secure linkability within the same service domain. Namely, in the interior of a service provider, a virtual index having a fixed value is calculated for each service user, and in this case, although a plurality of service providers collude with each other, they cannot calculate a virtual index having the same value, whereby the linkability can be secured within the same service domain but not within the interiors of different service domains.

A specific targeting peptide binding to glypican-3 can specifically binds to glypican-3 overexpressed in carcinoma cells and includes an amino acid sequence represented by SEQ ID NO:1 or some thereof. Glypican-3 is overexpressed in malignant tumors including hepatocellular carcinoma, melanoma, germ cell tumor, etc., and may be targeted in diagnosis and treatment of tumors by labeling the targeting peptide. A diagnosis using the specific peptide may detect even small tumors more accurately than conventional methods. A treatment method using the specific peptide may remove only carcinoma cells without harming other normal tissues.
