                'page callback' => "perso_personal_info", // after visit drupal6/person, person_personal_info() function is called
                'access callback' => true,  // must return true, otherwise it will not visible as menu item
                'type' => MENU_NORMAL_ITEM, // drupal's default menu type   
                'weight' => '10', // we want to display person link below in our nav menu
            );      
            return $items; // finally, do not forget to return $items array
        }
        function perso_personal_info(){
            $output = 'Name: Gaurav</br>';
            $output .= 'City: nanital </br>';
            $output .= 'Country: india </br>';
            return $output;
        }
        function person_permission(){ 
        return array(
         'administer my module' => array( 
        'title' => t('Administer my module'), 
        'description' => t('Perform administration tasks for my module.'),
         ), 
        ); }
        ?>

Please provide me the the code needed; it should work fine when I set the permission for my module.

You need to update "access callback" in your hook_menu in which users permission will be checked as below:

/**
 * implements hook_menu()
 */
function person_menu() {
  $items  = array();
  $items['person'] = array(
    'title' => "Person",
    'page callback' => "demo_custom_personal_info", // after visit drupal6/person, person_personal_info() function is called
    //'access callback' => true,  // must return true, otherwise it will not visible as menu item
    'access callback' => 'person_personal_info_check_access',
    'type' => MENU_NORMAL_ITEM, // drupal's default menu type   
    'weight' => '10', // we want to display person link below in our nav menu
  );
  return $items; // finally, do not forget to return $items array
}

Now you will need to add below function in you module file (this function will check user's access permission which will assign from permission page)

/**
 * To check user's permission
 */
function person_personal_info_check_access() {
  if (user_access('administer my module')) {
    return TRUE;
  }
  return FALSE;
}
