Abstract
A user authentication apparatus using a Raman spectrum is provided. The user authentication apparatus includes a Raman spectrum analyzer configured to analyze user characteristic information from a Raman spectrum of a user, and an authenticator configured to authenticate the user, based on the analysis.
Claims16
A user authentication apparatus using a Raman spectrum, the user authentication apparatus comprising:
- a light source configured to irradiate light to skin of a user, for a predetermined time;
- and
- a Raman spectrum acquirer configured to:
- receive that is reflected from the skin;
- and
- acquire the Raman spectrum of the user, from the light that is received;
- a Raman spectrum analyzer configured to analyze, in response to fluorescence bleaching occurring in the Raman spectrum over time:
- extract a fluorescence bleaching range from the Raman spectrum;
- and
- analyze the fluorescence bleaching range that is extracted, as user characteristic information;
- and
- an authenticator configured to authenticate the user, based on the user characteristic information that is analyzed.
