Abstract: A query string for an encrypted database storing a plurality of encrypted data records is received from a requestor. The query string is segmented to obtain at least one word. The at least one word is encrypted with the irreversible encryption algorithm to obtain at least one encrypted word. At least one first encrypted item with a co-occurrence weight higher than a preset threshold based on the at least one encrypted word and a co-occurrence statistics model is acquired. The co-occurrence statistics model is built to provide co-occurrence weights, each indicating a probability that the at least one encrypted word appears in a first encrypted data item of the plurality of encrypted data records. At least one second encrypted data item corresponding to the at least one first encrypted data item is acquired from the plurality of encrypted data records.

Abstract: Embodiments of the disclosure provide methods, systems, computer program products for accessing web pages interactively are disclosed. According to the method, a web page comprising a plurality of user interface elements is accessed. Then information comprising identifications of the plurality of user interface elements and hot keys corresponding to the plurality of user interface elements is obtained. And then the information is sent to an assistive tool for being read out. In response to a hot key corresponding to a user interface element being input, an action corresponding to the user interface element is executed.
