Abstract
Sending a search request includes: during a running procedure of a search engine client, generating a forged search request, where the forged search request carries a forged search word; and sending the forged search request to the search engine server. The forged search request is sent to the search engine server, to serve as a factor interfering with an analysis of a user behavior by the search engine server based on a true search request, to prevent the search engine server from analyzing the user behavior based on a search word entered by a user, thereby improving user experience.
Claims10
A method for sending a search request, comprising:
- during a running procedure of a search engine client:
- generating a forged search request, wherein the forged search request carries a forged search word;
- and
- sending the forged search request to the search engine server, wherein sending the forged search request to the search engine server comprises:
- sending a second search request to the search engine server at a first time, wherein the second search request is a forged search request or a true search request;
- and
- sending the forged search request to the search engine server at a second time, wherein there is a time interval between the first time and the second time, and the second search request is a search request previous to the forged search request, wherein the time interval t between the first time and the second time is determined by using a Poisson procedure, wherein the time interval t is determined based on a probability density function p(t;
- {circumflex over (λ)})={circumflex over (λ)}e−{circumflex over (λ)}t, where {circumflex over (λ)} is determined by using a maximum-likelihood estimation

- based on a time interval ti for sending the true search request, and N indicates a quantity of times of sending the true search request.
An apparatus for sending a search request, the apparatus comprising:
- a memory;
- a processor;
- and
- a transmitter;
- wherein the memory is configured to store an instruction,
- wherein the processor is configured to execute the instruction stored in the memory to generate a forged search request during a running procedure of a search engine client, wherein the forged search request carries a forged search word,
- wherein the transmitter is configured to send the forged search request generated by the generation module to the search engine server, and
- wherein transmitter is configured to:
- send a second search request to the search engine server at a first time, wherein the second search request is a forged search request or a true search request;
- and
- send the forged search request to the search engine server at a second time, wherein there is a time interval t between the first time and the second time, and the second search request is a search request previous to the forged search request, wherein the time interval t between the first time and the second time is determined by using a Poisson procedure, wherein the time interval t is determined based on a probability density function p(t;
- {circumflex over (λ)})={circumflex over (λ)}e−{circumflex over (λ)}t, where {circumflex over (λ)} is determined by using a maximum-likelihood estimation
