Abstract
Purpose
This paper aims to describe requirements for a model that can assist in identity deception detection (IDD) on social media platforms (SMPs). The model that was discovered demonstrates the usefulness of the requirements. The aim of the model is to identify humans lying about their identity on SMPs.
Design/methodology/approach
The requirements of a model for IDD will be determined through a literature study combined with a study that identifies currently available identity related metadata on SMPs. This metadata refers to the attributes that describe a user account on an SMP. The aim is to restrict IDD to be only based on these types of attributes, as opposed to or combined with the contents of a single or multiple communications.
Findings
Data science experiments were conducted and in particular supervised machine learning models were discovered that indeed detects identity deception on SMPs with an area under the receiver operator characteristics curve (ROC-AUC) of 75.5 per cent.
Originality/value
SMPs allow any user to easily communicate with their friends or the general public at large. People can now be targeted at great scale, most often for malicious purposes. The reality is that many of these cyber-attacks involve some form of identity deception, where the attackers lie about who they are. Much focus to date has been on the identification of non-human deceptive accounts. This paper focuses on deceptive human accounts that target vulnerable individuals on SMPs.

Abstract
Purpose
The purpose of this study is to show that a corporate brand with a long history coupled with relevance to the present obtains heritage-based value in society and the second aim is to examine a boundary condition in which the heritage-based value of a corporate brand increases the firm’s financial value.
Design/methodology/approach
A survey was conducted to investigate when and how a corporate brand obtains its heritage-based value in society and archival analysis was conducted to analyze the relationship between the heritage-based value of a corporate brand and the firm’s financial value.
Findings
The longevity of a corporate brand increased its heritage-based value, particularly when the brand was perceived to be temporally continuous, through the enhancement of authenticity perception and the heritage-based value had a positive effect on the firm’s financial value for younger firms.
Research limitations/implications
This study extends the benefits of the heritage association of a corporate brand to the firm level but has a limitation in its cross-sectional method.
Practical implications
The study results justify monetary costs incurred in the course of developing and cultivating a brand’s heritage association.
Originality/value
It is believed that this study is the first quantitative research examining the relationship between the heritage-based value of corporate brands and firms’ financial value.
