A sliding member having a hard carbon coating that has a thickness of 3 &#x3bc;m or more and demonstrates high peeling resistance and high wear resistance is provided. A sliding memberaccording to the present disclosure includes a base memberand a hard carbon coatingthat is formed on the base memberand has the hydrogen content of 3 atomic % or less and a thickness of 3 &#x3bc;m or more. When HM represents a Martens hardness of the hard carbon coatingand HIT represents an indentation hardness, the ratio HM/HIT is 0.40 or more.

Sliding member and piston ring

Provided is a sliding member having a hard carbon coating that makes high wear resistance compatible with a low coefficient of friction and that has excellent peeling resistance. A sliding member () includes a base member () and a hard carbon coating () formed on the base member (). The indentation hardness of the hard carbon coating () decreases gradually from the base member side to the surface side. The hard carbon coating () has an indentation hardness distribution at 0&#x2264;T/Ttotal&#x2264;0.6 approximated by a first line and an indentation hardness distribution at 0.9&#x2264;T/Ttotal&#x2264;1 approximated by a second line, and the intersection between the first line and the second line (T2/Ttotal, H2) satisfies Expression (1), (H3&#x2212;H1)&#xd7;T2/Ttotal+H1&#x3c;H2&#x2264;0.9&#xd7;H1, and Expression (2), 0.6&#x2264;T2/Ttotal&#x2264;0.9.

To provide an information processing apparatus, a server apparatus, a method of an information processing apparatus, a method of a server apparatus, and an apparatus executable program. An information processing apparatus uses signed integrity values unique to software configuration and asserting integrity of initial codes of a networked server. The server apparatus generates keys used for certifying the server apparatus (S, S, S). One of the keys are certified by a third party to generate a digital signature (S). The digital signature is attached to the integrity values and the signed integrity values are transmitted to the information processing apparatus for allowing the information processing apparatus to have secure services through the network (S, S).

The present invention creates a SOAP message without using DOM by generating a body part by sequentially performing such a process of a message as encryption or signing for each piece of the message, generating a header part by using information acquired during the process, and by combining the body part and the header part. The present invention also breaks a SOAP message without using DOM by acquiring header information with parsing a received SOAP message and sequentially performing decode or verification of a signature of a body part according to the header information.

Method for creating and processing a soap message, and method, apparatus and program for processing information

Provision of a technology capable of presenting information regarding derivative files secondarily derived and created from a leaked file, by retrieving the first leaked file, and capable of presenting personal information recorded on a computer accessible via a wide area network. There is provided an apparatus including a recording section for recording original data of a leaked file, an extracting section for extracting the original data and representations corresponding to information that should be prevented from being leaked and included in one or more files existing in a recording area to be investigated, an investigating section for investigating a degree of association between the file existing in the recording area to be investigated and the original data based on the extracted representations, and a presenting section for presenting information on a file created based on the leak.

Information presentation apparatus, and information presentation method and program for use therein

To prevent an input password from being stolen by an invalid authentication device. An authentication devicefor authenticating an inputter based on an input password accepted from the inputter is provided with a first input partfor allowing a first part of the input password to be inputted; a confirmation information output partfor outputting confirmation information known to the valid inputter in advance when the first partis valid, the confirmation information indicating to the user that the authentication device is valid; a second input partfor allowing a second part following the first part of the input password to be inputted; and a determination partfor determining that the inputter is valid when the first part and the second part are valid.

Authentication device, authentication system, authentication method, program and recording medium

To perform processing at a high speed to identify some of the structure type definitions in a given definition set to which a received XML document matches. There are provided a decision rule generation section which generates a decision rule for determining to which one of a plurality of DTDs an XML document matches on the basis of unique elements of the DTDs, and a DTD determination section which determines to which one of the plurality of DTDs the XML document to be processed matches on the basis of the decision rule generated by the decision rule generation section.

XML document processing for ascertaining match of a structure type definition

The invention includes a proxy server that constitutes means for providing, verifying and logging a digital signature for a message that is to be exchanged via a network, so that a security function for a digital signature can be implemented without changing an application program. In an example embodiment, a digital signature system comprises: applications for performing data processing; and a signature server connected to the applications via a LAN, wherein the signature server intercepts the message communication from the application to a destination device outside the LAN, provides a digital signature for a message document to be exchanged through communication, and transmits the obtained message document to the destination device.

Digital signature verification and program transmission

It is one object of the present invention to perform data compression to encode the structure part of a document in a tree local language, such as XML or ASN.1. A data compression apparatus for encoding data and for compressing the encoded data comprises: a grammar rulefor a tree local language in which data are represented by a labeled tree structure; an encoderfor reading a document written in the tree local language, for dividing the document into a structure part and contents, and for encoding the structure part using the grammar rule; and a compressorfor compressing the contents of the document extracted by the encoder, and for encoding the compressed contents.
