Abstract in simplified Chinese:在频率空间将消息信息藏入媒体信息中。因此对所藏入消息信息之去除及改变,给予高耐性,即使在利用频率滤波器之信号处理来实施的情形,也有效地继续保持所藏入消息信息。【解决方法】
为在媒体信息M中藏入消息信息m,将其等频率转变而求出该等频谱f1、f2。其次,由消息数据m之频率频谱f2,来抽出在消息信息m实数空间显示特征之具有特征频率成分的范围做为基本范围B。然后,就基本范围B而产生n个拷贝,在频率空间来分散配置n个拷贝,同时,其他之频率成分为零,产生频谱f3做为中间信息。最后,该频谱f3及频谱f1相加,该结果及频率转换,所以可在媒体信息M中藏入消息信息m。

Abstract:
Dynamic authorization based on focus data is provided to offer a mechanism for selecting an authorization routine, which is applied when the database query is executed, based on a focus of the database query. The database query including reference of a focus object for specifying the focus for the database query is received. The focus object is selected from a plurality of predetermined focus objects(402). Each focus object is defined by a plurality of data relations among data of a database. An authorization filter applied to the database query is selected among the plurality of authorization filters respectively corresponding to the focus objects based on the referred focus object(404). The selected authorization filter is applied to identify more than one condition added to the database query. The database query is modified to include more than one condition(410). The database query is executed to search a set of query results restricted by more than one condition added to the database query.
Abstract:
A method for assigning search ranking to a file system and a related search engine are provided to search the file system by using interaction between a user and a search engine system based on a structure of the file system. A file system energy tree index(610) records file system energy by using a tree structure corresponding to the file system and an energy score of each nodes of the tree structure. Each node corresponds to each file item of the file system. An energy tree updating module(606) updates the file system energy tree recorded in the file system energy tree index by responding to a task performed in the file system by the user. A search ranking assigning module(602) calculates the final suitability score of each file item for a query according to the energy score of each node recorded in the current file system energy tree index.
Abstract:
Determination of a date range for cached date-driven values is provided to process defects for filtering/caching the recurring date-driven data and determine the date range of the cashed date-driven values. A date range is defined and three cached instances are searched from date-driven data for each recurrence(220). Only the recurrences included in the date range are selected by three cached instances. The selected recurrences are added to a subset of the date-driven values(250). The remaining recurrences are excluded from the subset of the date-driven values(290). The date range is restricted by the first and last time point.
Abstract:
An information processing apparatus and an information processing method are provided to offer a user interface capable of operating a plurality of applications in common, thereby improving the possibility of access by the visually handicapped. An information processing apparatus(10) comprises the followings: a document converting unit(22) which converts an instinct document, which is written by each of a plurality of applications and is shown to a data structure of each application program, into a common document(200) shown to a common data structure; an output unit(28) which outputs the common document to a user; an input unit(28) which inputs the operation of the user for the common document; an interface adaptor unit(30); a changing unit(22); and a change reflecting unit(32).
Abstract:
A method for aligning a semiconductor device structure is provided to align efficiently even a first mark set by forming first and second align mark sets in the same mask level. A first align mark set(106a) is formed in the lower level of a semiconductor device structure, and a second align mark set(106b) is formed near the first align mark set. An opaque layer is formed on the lower level of the semiconductor device structure including first and second align mark sets. A part of the opaque layer corresponding to the position of the first align mark set is opened so that the first align mark set is optically monitored and the second align mark set is left as the second align mark is initially covered with the opaque layer. The opaque layer is lithographically patterned by using the optically monitored first align mark set. The first and the second align mark sets can include both align marks(102) and overlay boxes(104).
Abstract:
A system, a method, and a medium for processing a spreadsheet to store the spreadsheet to a database are provided to process/store the spreadsheet to the database by automatically processing records of the spreadsheet and applying a conventional validation/business process logic. A request for processing the spreadsheet including a plurality of records to store the spreadsheet to the database is received(502). A configuration file related to the spreadsheet is generated by receiving more than one name of a business object related to the record of the spreadsheet, metadata for more than one column of the spreadsheet, and the name of a back-end business component related to the spreadsheet. The generated configuration file is accessed(508). A new business object is generated for each record of the spreadsheet, and is populated based on the records and the configuration file(514). Each new business object is transferred to a back-end business application(516).
