Michael Goldberg, certify that:
 
 1. I have
reviewed this Annual Report on Form 10-Q of IDO Security Inc. for the quarter
ended September 30, 2008.
 
 2. Based on my
knowledge, this annual report does not contain any untrue statement of a
material fact or omit to state a material fact necessary to make the statements
made, in light of the circumstances under which such statements were made, not
misleading with respect to the period covered by this report;
 
 3. Based on my
knowledge, the financial statements, and other financial information included in
this report, fairly present in all material respects the financial condition,
results of operations and cash flows of the registrant as of, and for, the
period presented in this annual report;
 
 4. I am
responsible for establishing and maintaining disclosure controls and procedures
(as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) and internal
control over financial reporting (as defined in Exchange Act Rules 13a-15(f) and
15d-15(f)) for the registrant and I have:
  a) designed such
disclosure controls and procedures, or caused such disclosure controls and
procedures to be designed under my supervision, to ensure that material
information relating to the registrant, including its consolidated subsidiaries,
is made known to me by others within those entities, particularly during the
period in which this report is being prepared;
  b) designed such
internal control over financial reporting, or caused such internal control over
financial reporting to be designed under my supervision, to provide reasonable
assurance regarding the reliability of financial reporting and the preparation
of financial statements for external purposes in accordance with generally
accepted accounting principles;
  c) evaluated the
effectiveness of the registrant's disclosure controls and procedures and
presented in this report my conclusions about the effectiveness of the
disclosure controls and procedures, as of the end of the period covered by this
report based on such evaluation; and
  d) disclosed in this
report any change in the registrant’s internal control over financial reporting
that occurred during the registrant’s most recent fiscal quarter (the
registrant’s fourth fiscal quarter in the case of an annual report) that has
materially affected, or is reasonably likely to materially affect, the
registrant’s internal control over financial reporting;
 
 5. I have
disclosed, based on my most recent evaluation of internal control over financial
reporting, to the registrant's auditors and the audit committee of the
registrant's board of directors (or persons fulfilling the equivalent
function):
  a) All
significant deficiencies and material weaknesses in the design or operation of
internal control over financial reporting which are reasonably likely to
adversely affect the registrant's ability to record, process, summarize and
report financial information; and
  b) Any
fraud, whether or not material, that involves management or other employees who
have a significant role in the registrant's internal control over financial
reporting.
