  • Patent number: 7949940
    Abstract: A data entry restriction program capable of rejecting invalid structured documents out of structured documents of a general-purpose format with great flexibility. When a structured document is entered, a data entry restriction apparatus compares the structure of the structured document with flexibility requirements (step S1). When the structured document does not meet the flexibility requirements, the data entry restriction apparatus records error information in association with the sending client of the document (step S2). After the error information associated with the client exceeds prescribed limits, the data entry restriction apparatus rejects structured documents from the client (step S3). Structured documents which meet the flexibility requirements and the data entry restriction apparatus has accepted are entered into a data processing apparatus and analyzed (step S4).
