A method for rewriting source text includes receiving source text including a source text string in a first natural language. The source text string is translated with a machine translation system to generate a first target text string in a second natural language. A translation confidence for the source text string is computed, based on the first target text string. At least one alternative text string is generated, where possible, in the first natural language by automatically rewriting the source string. Each alternative string is translated to generate a second target text string in the second natural language. A translation confidence is computed for the alternative text string based on the second target string. Based on the computed translation confidences, one of the alternative text strings may be selected as a candidate replacement for the source text string and may be proposed to a user on a graphical user interface.

Keyboard for one-handed touch typing derived from a normal Sholes keyboard, where each character-key is assigned two characters (for instance T / Y), thereby reducing the number of keys to approximately half the number of keys on a normal Sholes keyboard. The choice between the two alternative characters of a specific key is based on the mode of depression of that particular key, and hence no separate key for choise between the two alternatives is needed. The characteristics of the keyboard can either be set once and for all or can be particularly adapted to the specific user of the keyboard, such as for instance to the user's writing speed.

A method for determining if a user of a computer system is a human. A processor receives an indication that a computer security program is needed and acquires at least one image depicting a first string of characters including at least a first and second set of one or more characters. A processor assigns a substitute character to be used as input for each of the second set of one or more characters. A processor presents the at least one image and an indication of the substitute character and when to use the substitute character to the user. A processor receives a second string of characters from the user. A processor determines whether the second string of characters substantially matches the first string of characters based on the substitute character assigned to each of the second set of one or more characters and determines whether the user is a human.

Method to prevent the effect of web application injection attacks, such as SQL injection and cross-site scripting (XSS), which are major threats to the security of the Internet. Method using complementary character coding, a new approach to character level dynamic tainting, which allows efficient and precise taint propagation across the boundaries of server components, and also between servers and clients over HTTP. In this approach, each character has two encodings, which can be used to distinguish trusted and untrusted data. Small modifications to the lexical analyzers in components such as the application code interpreter, the database management system, and (optionally) the web browser allow them to become complement aware components, capable of using this alternative character coding scheme to enforce security policies aimed at preventing injection attacks, while continuing to function normally in other respects. This approach overcomes some weaknesses of previous dynamic tainting approaches by offering a precise protection against persistent cross-site scripting attacks, as taint information is maintained when data is passed to a database and later retrieved by the application program. The technique is effective on a group of vulnerable benchmarks and has low overhead.

An information processing apparatus capable of reliably accessing files associated with file identification information generated based on more character code systems, without necessitating a large-capacity memory. When the information processing apparatus (MFP) acquires file identification information, a CPU of the MFP determines whether or not the MFP is capable of performing processing based on a predetermined character code system used for describing the identification information. When the MFP is not capable of performing processing based on the character code system, the CPU converts the identification information described in the predetermined character code system into substitute character codes processable thereby. Then, the CPU registers the substitute character codes and the original character codes before the conversion in a map table in association with each other. When the processing on the file is completed, the CPU deletes the substitute character codes and the original character codes from the map table.

A method and apparatus is used to of validate a vehicle identification number (VIN). At least a first VIN having a plurality of characters in a plurality of positions is received. At least a first character in a first position of the first VIN to inspected to determine if the first character is included in a first set of valid characters. The first character is identified as being in error when the first character is not in the first set of valid characters. The first character is replaced with a substitute character.

An in-place data input panel provides a user with access to a list of alternate characters to which displayed characters may be converted. The data input panel provides an indicator, such as an indicator bar, corresponding to segmentation of the characters. A user can change the segmentation of the characters by expanding or contracting the segmentation bar. Also, the user can access a drop-down menu listing alternate character choices corresponding to the characters in the segment indicated by the segmentation bar.

The utility model relates to a way and a system to add appellations of target users when mass-sending messages, which is to add individual appellations of target users automatically when mass-sending messages by use of the function module of mass-sending messages. Firstly, the mobile numbers and the appellations of target users are added to the communication list provided with the message send-receive terminal device by the user; then when compiling a mass-sending message, substitute characters required as an uniform regulation of the system are inputted in the positions where individual appellations of target users are to be presented; after the mass-sending message is well compiled, select mobile phone numbers for different target users from the communication list provided with the message send-receive terminal device and mass-send the message. Meanwhile the message mass-sending function module of the message send-receive terminal device receives the order of sending out the message; if substitute characters are detected, the substitute characters will be replaced with appellation of target users in the communication list corresponding to the phone mobile numbers of the target users; and then the message is sent out.

Every Chinese character belongs to a small graphic form group which is created with respect to the radical of the character instead of character components. Every small graphic form group is incorporated into higher-level groups, i.e. medium graphic form groups, in turn every medium graphic form group is incorporated into higher-level groups, i.e. large graphic form groups. Input guidance is provided according to this hierarchy concerning graphic form. More specifically, the large groups are presented and one of them is selected by the first keystroke, the medium groups are presented and one of them is selected by the second keystroke, and the small groups are presented and one of them to which the desired character for input belongs is selected by the third keystroke. In this fashion, three keystrokes to a numeric keypad efficiently narrows down the alternative characters for conversion.

A compression file formed by compressing an object file is compared in a compressed state with a compression code string that matches with a compression character string of a character string to be searched for. The compression code string acquiring no match as the result of the comparison is decompressed as it is. On the other hand, the compression code string acquiring match is substituted with a substituted character string in a comparison and substitution table generated in advance.
