The present invention discloses a method and an apparatus for processing an authentication of a mobile terminal, wherein the method includes: a network side receiving an image identity message from a mobile terminal, wherein the image identity message carries current image feature information and a user identifier of the mobile terminal; and searching image feature information which is saved previously in a database by the user identifier of the mobile terminal, performing a corresponding algorithm match between the current image feature information and the image feature information according to a preset security level, and performing an authentication on the mobile terminal based on the result of the match. By means of the technical solution of the present invention applying, the image information collected by photo shooting is used as an identity identification password, therefore, the identity authentications of different security levels can be provided, and the security and the expansibility of the identity authentication of the mobile terminal is increased greatly.

A relay server which is connected to a LAN and which can communicate with a relay server in a different LAN, includes: an account information registering unit that stores information on client terminals connected to the LAN; a relay group information registering unit that stores relay group information; a shared resource information registering unit that stores shared resource information; a check unit that checks whether the client terminals stored in the account information registering unit can be accessed; a relay group information notifying unit that updates the relay group information and transmits a change notification of the relay group information to the relevant relay server; and a shared resource information notifying unit that updates the relevant shared resource information and transmits a change notification of the shared resource information to the relevant client terminal which is stored in the account information registering unit.

This high strength hot rolled steel sheet has a predetermined chemical composition, in which the structure of the high strength hot rolled steel sheet contains martensite in an area ratio of 20% or more and 60% or less and ferrite in an area ratio of 40% or more, and the total area ratio of the martensite and the ferrite is 90% or more, the average grain size of the martensite is 5.0 μm or more and 50 μm or less, the ratio of the hardness of the martensite to the hardness of the ferrite is 0.6 or more and 1.6 or less, and the tensile strength of the high strength hot rolled steel sheet is 980 MPa or more.

A steel sheet wherein a steel structure of an inside of the steel sheet contains, by volume fraction, soft ferrite: 0% to 30%, retained austenite: 3% to 40%, fresh martensite: 0% to 30%, a sum of pearlite and cementite: 0% to 10%, and a remainder including hard ferrite. In the steel sheet, in a ⅛ to ⅜ thickness range, a proportion of retained austenite having an aspect ratio of 2.0 or more is 50% or more, and a soft layer having a thickness of 1 to 100 μm from a surface in a sheet thickness direction is present. When an emission intensity at a wavelength indicating Si is analyzed in the sheet thickness direction from the surface by a radio-frequency glow discharge analysis method, a peak of the emission intensity appears in a range of more than 0.2 μm and 5.0 μm or less from the surface.

A steel sheet has a chemical composition with a steel structure containing, by volume fraction, soft ferrite: 0-30%, retained austenite: 3-40%, fresh martensite: 0-30%, pearlite and cementite: 0-10%, and a remainder including hard ferrite. In the steel sheet, a number proportion of retained austenite having an aspect ratio of 2.0 or more in the total retained austenite is 50% or more, and a soft layer having a thickness of 1-100 μm is present. In the soft layer, a volume fraction of ferrite grains having an aspect ratio of less than 3.0 is 50% or more, and a volume fraction of retained austenite is 50% or more of the volume fraction of the retained austenite of the inside of the steel sheet. A peak of an emission intensity at a wavelength indicating Si appears in a range of more than 0.2 μm to 5 μm or less from the surface.
