         2 . The file viewing system according to  claim 1 , wherein the comparison unit performs the comparison when the comparison target person performs an operation for viewing the electronic file. 
     
     
         3 . The file viewing system according to  claim 1 , wherein the comparison unit performs the comparison after the comparison target person performs an operation for viewing the electronic file and during a period when the comparison target person can view the electronic file. 
     
     
         4 . The file viewing system according to  claim 1 , wherein the viewing prevention unit performs a process for preventing the comparison target person from viewing the electronic file by displaying a mask pattern that is overlaid on a content of the electronic file displayed on a display device and that prevents the content from being viewed. 
     
     
         5 - 6 . (canceled) 
     
     
         7 . The file viewing system according to  claim 1 ,
 wherein the content of the electronic file includes a first portion to which a viewing restriction for the comparison target person is applied and a second portion to which a viewing restriction for the comparison target person is not applied, and   wherein the viewing prevention unit performs a process for preventing the comparison target person from viewing the electronic file only in the first portion.   
     
     
         8 . The file viewing system according to  claim 7 , wherein the first portion and the second portion are divided based on a degree of confidentiality of the content. 
     
     
         9 . The file viewing system according to  claim 1  further comprising a log generation unit that generates a log including information indicating that the comparison target person has viewed the electronic file based on a result of a comparison by the comparison unit. 
     
     
         10 . The file viewing system according to  claim 9 ,
 wherein the content of the electronic file includes a signature field, and   wherein the log includes information indicating whether or not the person to sign the signature field is the comparison target person.   
     
     
         11 . The file viewing system according to  claim 1  further comprising a sight line detection unit that detects a sight line of the comparison target person,
 wherein the viewing prevention unit performs a process for preventing the comparison target person from viewing the electronic file based on the sight line. 
 
     
     
         12 . The file viewing system according to  claim 11 , wherein the viewing prevention unit performs a process for preventing the comparison target person from viewing the electronic file when the sight line is outside the content of the electronic file. 
     
     
         13 . The file viewing system according to  claim 11  further comprising a log generation unit that generates a log indicating whether or not the comparison target person has viewed a predetermined portion of the content of the electronic file based on the sight line. 
     
     
         14 . The file viewing system according to  claim 1 ,
 wherein viewing authority of the person is set based on an attribute of the person, and   wherein the viewing prevention unit performs a process for preventing the comparison target person from viewing the electronic file based on the viewing authority corresponding to the attribute of the comparison target person.   
     
     
         15 . The file viewing system according to  claim 14 , wherein the attribute of the comparison target person includes at least one of an affiliation of the comparison target person and a job title of the comparison target person. 
     
     
         16 . The file viewing system according to  claim 1 ,
 wherein the comparison unit performs a comparison for each of a plurality of comparison target persons who intend to view the electronic file;   wherein the viewing prevention unit performs a process for preventing viewing of the electronic file when at least one of the plurality of comparison target persons does not have viewing authority;   
     
     
         17 . The file viewing system according to  claim 16  further comprising a sight line detection unit that detects a sight line of each of the plurality of comparison target persons,
 wherein the viewing prevention unit performs a process for preventing viewing of the electronic file based on the number of comparison target persons whose sight line is outside the content of the electronic file. 
 
     
     
         18 . The file viewing system according to  claim 1  further comprising:
 a valid period acquisition unit that acquires a valid period set in the electronic file; and 
 a time acquisition unit that acquires a current time, 
 wherein the viewing prevention unit performs a process for preventing the comparison target person from viewing the electronic file when the current time is outside the valid period. 
 
     
     
         19 . The file viewing system according to  claim 1 ,
 wherein the comparison unit performs a first comparison when the comparison target person performs an operation for viewing the electronic file, and performs a second comparison during a period when the comparison target person can view the electronic file, and   wherein, in the first comparison and the second comparison, thresholds that are references for comparison of the comparison target person is different from each other.   
     
     
         20 . The file viewing system according to  claim 1 , wherein the biometric information is a face image of the comparison target person or a feature amount generated from a face image of the comparison target person. 
     
     
         21 . A file viewing method comprising:
 comparing biometric information of a comparison target person with biometric information of a person associated with an electronic file; and   performing a process for preventing viewing of the electronic file based on a result of the comparison.   
     
     
         22 . A non-transitory storage medium in which a program is stored, the program causing a computer to execute a file viewing method comprising:
 comparing biometric information of a comparison target person with biometric information of a person associated with an electronic file; and   performing a process for preventing viewing of the electronic file based on a result of the comparison.
