                var web = properties.Feature.Parent as SPWeb;

                

                    using (web)

                    {

                        web.AllowUnsafeUpdates = true;

                        SPFile page = web.GetFile(web.Url + "/" + relativeUrlOfPage);

                        if (page.Exists)

                        {

                            SPServiceContext serviceContext = SPServiceContext.GetContext(web.Site);

                            AudienceManager audienceManager = new AudienceManager(serviceContext);

                            SPLimitedWebPartManager wpManager = web.GetLimitedWebPartManager(page.Url, System.Web.UI.WebControls.WebParts.PersonalizationScope.Shared);

                            foreach (System.Web.UI.WebControls.WebParts.WebPart wp in wpManager.WebParts)

                            {

                                if (wp.Title.ToLower().Equals("YourWebpartTitle"))

                                {

                                        wp.AuthorizationFilter = string.Format("{0};;;;", Your GroupName/UserName);

                                        wpManager.SaveChanges(wp);

                                   

                                }

                            }
